To tell the truth, I'm pretty disappointed with my MAILORDER TUNERS experience...
Because I should have done it much sooner ! My little sleeper of a truck is fully awake now..... I always liked how it performed. With just a few power adders she was running pretty strong. But I never would have guessed how much more she had to give...... now that I let the tune masters @ MAILORDER TUNERS do their magic........ Holy Hell Ya!! Those gurus are BOSS ! They got my tune on point and crazy as it seems , it got done by mail. Simply amazing..... they got my truck in straight up Beast Mode.
So nice when the outcome is exactly what you where told it would be.
If you have been thinking about trying MAILORDER TUNERS out.... your going to be pissed you didn't do it sooner. These guys are the real deal, for real,real. My turn around time was a total of 3 days and that includes the day I sent it off...
One other bad thing about using MAILORDER TUNERS,,,,, Now most of my neighbor's hate me, but I'm lovin it.
So do yourself a favor and get MAILORDER TUNERS on your team.

Had my truck tuned locally but just didn’t run as expected. Overnighted ecm to mailordertuner.com with my build info. 3 days later had it back & installed. Incredible difference. Truck runs awesome. Will use them for all my tuning going forward. Thanks!!
Jacob G.
Started right up and tune seems perfect.
Joseph G.
Tuners was just what I needed to get my build rolling
Justin M.
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!
Matthew C.
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.

Good tunes
Billy B.
Response time and customer service was excellent, couldn’t be happier, I had a problem on my end while tuning and I couldn’t figure it out, he offered for me to come to his shop and upgrade and tune in person and they got right on me and got me right out , Casey was very nice and professional, only place I’ll go now
Tyler B.
This is the second time I’ve worked on getting my truck tuned with Casey and let me tell ya I got zero complaints. extremely easy to work with and will walk you through your first time. 1st tune was for a cam then a retune for a high stall converter. I always get a response next day after every log or base tune! He’s got the truck dialed right in and it’s a beast. I would never switch tuners and I would highly recommend to anyone that reads this to let this be your sign to use Casey as your tuner!
John W.
Great Service will use again
Leater P.
Ordered tune for my cammed Silverado and performs very well. I the. Ordered a tune for my brothers Silverado and he is happy as well.
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!

Texas Speed and Performance "Low Lift" Cam and Springs Package
Regular price
$483.99
Save $-483.99
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.

Texas Speed Low Lift 212/218, .550/.550 Camshaft With Your Choice of Lobe Separation
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.
