I have a 1998 Cheyenne that is used for towing a 5th wheel camper. Truck has 110,000 miles and overall is in great shape for her age. Manual transmission. Not sure of the rear end gearing. 7.4L is running good. Stock tune, no upgrades have been done to the engine.
I’m interested in your tuned ECM. What kind of performance can I expect with your tuned ECM? Will “Check Engine” lights still operate? Would changing injectors help with this tune? Looking to beef her up a bit without sacrificing reliably.
Thanks. ( Michael Wernecke, 06/27/2023 )

You can expect a boost of around 40 horsepower and 45 lb-ft torque with our tuning. All functions such as the check engine light will still operate as normal. We do see some improvement by upgrading to a Bosch fuel injector: https://www.fiveomotorsport.com/bosch-oem-454-j-code-884-black-knight/

I have a 2000 c6500 with a l21 454 it's similar to the l29 but has coil near plug ignition and uses a ls1 ecu as far as I know. I need to get a bump in power out of this thing and can send in the ecu if it's something you can tune. I'd also like to disable all emissions. The truck has no factory cats but does have egr.

We do not offer tuning for this platform due to availability of ECM's for them. If the ECM were to be damaged or lost in shipping, it would be extremely difficult to find a replacement.

I am wanting to upgrade my 1996 k2500 suburban ecm with a 1998 ecm from a K2500 pickup. If i send you the 1998 ecm can you progrom it to work for my 1996 suburban ( David Nardi, 06/11/2023 )

I'm sorry but we can't configure the 98-00 PCM to work on a 1996 truck.

99 K3500 Vortec 7.4L. shorty headers, Bosch D3 injector upgrade, primarily used as daily driver & camper towing.

Have you done any tunes for a Vortec 7.4L with the camshaft installation advanced? Stock these engines are retarded to about 118 degrees, I purchased a new adjustable timing set and plan on advancing my cam to 108, possibly 106. Will this work, and can you tune for this?

Thank You! ( Stacey, 06/09/2023 )

It cannot be tuned for that because it'll set a Cam to Crankshaft position error. You'd have to have a camshaft that's ground correctly for the cam sensor reluctor position change, or it'll set a sync error.

1999 Chevy K2500, 7.4l 454 Vortec with AC 3.73 gear ratio LT265/75R16 tires 4L80E trans I am mainly looking to make the truck run as efficiently as possible with a good balance of power and efficiency. I will eventually tow a small-ish boat and trailer to haul construction debris but this truck will mostly be used for house projects and elk hunting. What are your thoughts on the tune? Anything else you need to know? Other than repinning, is there another benefit to going with this option/tune over a 0411 PCM swap? ( Tim Irving, 05/30/2023 )
