Due to lifter failure damaging my TSP cam,I went back with the L8T cam which prompted a retune.Tune was perfect.Truck drives and shifts smooth!Very happy with the quick turnaround

Had good luck with their service in the past, mid lq4 build, my daily L86 had lifter failure.
Pulled ecm and ordered complete dod delete kit from them. Shipped off ecm, got all parts and ecm back in time to start up the truck.
Shipped ecm and ordered kit, tore down same weekend, kit showed up during the week began assembling, and ecm was there Saturday. Ran perfectly.
Only regret, still on the fence if I should have got a bigger cam or not.
Thank you again team for the great service.

I bought this truck not running with the understanding that i might need a new engine. I rebuilt it l, went .020 over due to an out of round bore. All new pistons, rods, and crank and a Texas Spped AFM/DOD delete kit with Stage 2 cam. I just installed the engine and got it running about 2 weeks ago. I'm still working out some issues, when the engine warms up my oil pressure drops from 45psi at start-up down to 16-18 psi when at 210 degrees. I installed a stock replacement GM pump, I may need a high volume hi pressure pump?? My main bearing clearances were .002" and its an aluminum block. Im looking for any suggestions.
As far as the transmission, its all over the map. From the looks of things it was rebuilt prior to me purchasing the truck and it was never filled with trans fluid and ran at all. The torque converter was empty and spotless inside along with the pan, nothing at all in there either.
Initially I didnt have 4th gear, based on articles and videos I saw I drained and dropped the pan and did a solenoid check with my scan tool. The #8 & #9 solenoid connectors were swapped. That some what fixed my issue with 4th gear but I have to let off the gas to allow the trans to shift. Any recommendations are appreciated. Thanks. I will gladly update my review once I work all the bugs out.

Sent them my ecm since I did a DOD delete on my silverado. I received a notification from ups that they received my computer in the morning and later that afternoon I received another notification that my unit was ready to be shipped back out to me. Super fast turn around and everything seems to.be doing ok. Will definitely order a hp tuner from them and start getting email tunes tho. Just like a little kid, I dont like waiting for stuff and email tune will arrive eve. Faster . Thanks again guys! You rock.
