My truck is a 98 C2500 with the L29 and manual trans. You mention tuning that changes shift points in auto trans. Do you have a tune for manual transmissions?( Mike G., 06/17/2026 )
We can tune the engine, there are no changes made to the transmission since it's a manual.
Hello I was just curious as to why you no longer tune 96-97 vortec 454's ? Is their something different about them years ? I ask because i was going to purchase a truck with a vortec 454 in the next week or so and would like to use your service and wanted to ask that before i buy a certain model year.( John baker , 02/23/2025 )
The issue is not that we can't actually program them, it's that the ECM's used on the 1996-1997 trucks have proven to be troublesome in getting a good unit or having them ship and arrive without any issues.
I have a 98 gmc sierra k3500. I have install a cam, rocker arms. Underdrive pullie cold air intake and 3in exhaust all the way out . 4 in lift kit on 33s .it doesn't have cats anymore or smog pump. I use this truck in our 100 acres property . To move heavy equipment and trailers from one side to another. My question is if I purchase your tunning will you ship it to California? The truck never see pavement .( Stevan , 01/30/2025 )
Unfortunately, even with it being an "off road use only" vehicle, we are not allowed to ship this product into California.
I have a 2000 c3500hd dumptruck manual transmission 7.4l cats have been removed at some point. Only used for towing/hauling. It could use some more power will this help? ( BEN STABLER, 01/24/2025 )
Yes, we can tune this truck/engine and gain good power out of it.
Looking at purchasing a 99 l29 454 and 4l80e to install in a 90 c3500. What all can you do to help with this swap. All stock programming now. I believe it's out of a motor home but not sure. ( Jeremy , 12/14/2024 )
We can assist with disabling security/VATs and other unneeded control systems. We do not provide general technical assistance in engine swaps but we can answer questions in regards to the programming.
