I installed a summit stage 2 cam in my 2003 4.8 Silverado and needed a tune. My ECM made it to Texas on a Wednesday morning and Casey called me to go over a few things about my truck and they shipped my computer that evening. I got it a couple days later and installed it in my truck. It fired right up and runs awesome! Sounds like a racecar just like Casey said it would!
Brandon B.
Sent in my ECU to mail order tuner and had them tune it and they had a very fast turn around. Got it back in and it drives awesome! And no more check engine light for the O2’s!

Needed a custom tune to get my 1997 k1500 with a gen 3 5.3 ls swap up and running and the crew at mail order tuner did not dissapoint. My computer was retuned and on its way back to me the same day it arrived and they even called me with a couple questions to make sure everything was done right the first time. Great company would highly recommend for all tuning needs
Raymond S.
Excellent service, fast turnaround, works perfectly
juan r.
Great services externally fast turn around time. The only thing would be the need to up their packaging. I know it's the mail carriers fault but 1 bubble wrap envelope would protect my ECU from damage. It still works but it's damaged now.

Tim G.
Did a lot of research on email tunes and who was the best. I saw he tunes for Texas speed and knew I would be in good hands. I wanted to build a sleeper and it is just that. I originally got a tune for just a cam. I put a turbo on and he got that dialed in pretty fast. I had a couple of problems on my end. He instantly had an answer to everything and told me how to fix it. My truck runs great and I wouldn’t trust anybody else tune it!

Robert K.
Great knowledgeable service. Any questions or issues I had were quickly resolved. Would definitely recommend their tunes for anyone needing one.
Angelo G.
Beside the fact UPS losing my original computer and having to buy a new one MOT hooked it up and tuned my new ecu for free and paid for 2 day shipping, the best customer service I have ever dealt with in my life, the tune has made the trucks cam even more mean sounding and responsive than I would have expected. I would choose MOT over any local shops around me, that would charge me double the price for a junk tune and the truck probably wouldn’t run right but I would highly recommended this company forsure!

Chevrolet Performance LS7 lifter set is an OE hydraulic roller lifter that can be used in all non-DOD LS and Gen 5 LT engines.
LS7 Lifters – (FAQ’s) Frequently Asked Questions
Mail Order tuner proudly supplies the natural LS7 lifters for LS engines. These lifters are the perfect replacement of the standard lifters known to start as noisy- Often with a sound and evolve into much more of an issue. LS7 lifters prevent damaging the hydraulic camshaft and causing expensive labour and help save our time and headaches with other filters.
Lifters in factories are loaded with springs, and the problem occurs in these loaded lifters and is famous for failing and crucially eating away the camshaft. This can lead to severe problems that can easily be prevented by upgrading the LS7 lifters. These wrong locations and preload result in open values, and therefore this leads to loss of power. These filters are designed to replace the standard filters and will surely suit all LD engines in your factory. We assure you that all our products are manufactured with high-quality material on which you can trust the reliability and performance of the LS-powered vehicle.
Texas Speed and Performance "Low Lift" Cam and Springs Package
Regular price
$397.99
Save $-397.99
This camshaft package is specifically for the Texas Speed low lift truck camshafts that can use the GM LS6 single beehive valve springs. You will not find a better price on a cam package than this one! Very economical with respectable horsepower and torque gains, and these camshafts will not be overly radical. Tuning is Required for aftermarket camshafts.
This Package Will Include the Following Items:
Your Choice of TSP Low Lift Camshaft
GM LS6 Single Beehive Valve Springs, Set of 16, #28-12499224
You can see the power gains below (measured at crank) for each of our camshafts over a factory 5.3L camshaft that we tested on our in-house SuperFlow 902 engine dyno:
Stage 1 208/214: +45.1 HP & +21.5 TQ
Stage 2 212/218: +51.4 HP & 22.9 TQ
Stage 3 216/220: +53.4 HP & 22.0 TQ
Keep in mind that these gains are compared at the peak HP and TQ numbers. Our cams gained as much as 70+ HP and TQ at other points in the dyno graph, and NONE of these camshafts lose any HP or TQ at 2,000 RPM! You can see each of the dyno graphs for each camshaft listed on our website.
You will reuse your factory retainers, locks, seats, and seals, as well as your factory pushrods! You may need to change to a different length pushrod if you change to a different style of lifters at the same time. Some lifters do vary in overall length.

This cam gained 51.4 HP and 22.9 TQ at the flywheel on our in-house SuperFlow 902 engine dyno using an otherwise stock 5.3L engine!
This cam uses proprietary TSP lobe profiles that are designed to utilize the factory GM LS6 single beehive valve springs and your factory pushrods, making them the most affordable cam package on the market!
1200-5800 RPM Power Band; This is an excellent performance camshaft with a smooth idle! We've had tons of customers select this camshaft when looking for a cam that drives almost stock, and can be practically hidden with some exhaust systems! If you're looking for a small, stealth camshaft the 212/218 is a great option to consider. It is ideal for 4.8L and 5.3L trucks that want to keep their factory torque converter and not break the bank on more expensive valve springs and pushrods.
Texas Speed and Performance Dual Spring Cam Package

Your Choice of Camshaft, TSP Spring kit, and Hardened Chromoly Pushrods
This Package Includes the Following Items:
Your Choice of Camshaft
Includes TSP .660" Dual Spring Kit w/ PAC Racing Polished Springs, Titanium Retainers, Hardened Spring Seats, and New Valve Stem Seals
Texas Speed Hardened Chromoly Pushrods
We have two options listed for our dual valve spring kits. The default option will use our PRC integrated one-piece seat and seal that simply pushes in place. The other option is for the separate two-piece seat and seal that you typically find in any dual valve spring kit. The two-piece kit will require separate installation of the valve seals after the seats are in place, and it does require a specific tool to make sure that the valve seals are installed properly (i.e. not crooked, torn, or not installed fully). Our integrated seat and seal will make your installation much easier because it is virtually impossible to install it incorrectly! You can choose either kit for no additional charge. We have a picture listed when you select each spring kit so you can see the actual differences in the two kits.
This is the perfect upgrade package for customer looking for all the aftermarket parts needed to do a camshaft swap. Typical gains will range from 30 to 65 rear-wheel horsepower from a TSP camshaft swap alone!
We do offer the optional adjustable pushrod length checker that allows you to verify the correct pushrod length needed for your setup. We can give you a good idea of what is typically used with your engine, lifter brand, etc., but it can certainly vary from setup to setup. You can vary up to .050" in pushrod length depending on which camshaft core the cam manufacturer uses! This is NOT information that any camshaft manufacturer includes with their camshafts, so it is always best to verify the length you need to avoid any valvetrain issues.
Because we cannot stock every camshaft with every lobe separation angle, if you need parts quickly, we encourage you to call us to check availability of the camshaft you want. The LSA(s) we typically stock for each camshaft is listed next to each camshaft. Some camshafts will have to be custom ground and drop-shipped from the manufacturer directly to you!
