Is it possible to install the Bosch injectors at a later date without reprogramming the ECM?
( Michael Wernecke, 06/29/2023 )
Yes, the injectors do not require different programming.
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.

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

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!

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.
