I have a 1996 Suburban K2500 with the L29 engine and 4l80 trans. Do you still tune the 96 ecm? I read in earlier questions asked that you had stopped doing the earlier ones. Thanks. ( Steve E Schueler, 06/13/2021 )

We have been doing them on a limited basis, it has been very challenging to find good cores to use. If you want to send your PCM in that you know is functional, that is the best way to do it.

The vin is for a 2004 gmc 1500 with a 5.3 vortec. I recently ordered an ecm for a 7.4 vortec and was very impressed. Do you offer anything for the 5.3?

Thanks,

We appreciate it but we only specialize in the big block engines.

I own a 1998 Safari Trek 2830 P32 chassis with an L29... 28'7" Class A RV... Drivetrain it s completely OEM.. I am in a non emissions state...

My priority is s MPG

Your literature recommends bosch 4 hole injectors..

I have no issues deleting cats... Or deactivating o2 sensors...

What other parameters do you recommend I request for maximum mpg when I send my ECU to you?

When I buy my banks power pak from you and add water injection and propane injection... Will my ECU need to be reprogrammed again?

Currently I flat tow a 96 Toyota 4runner... I use a Suntune econometer gauge to stay in vacuum... Mpg's are 9.6 - 11.2 flat towing on 87 octane

Your literature states .5-1.5 mpg improvement... With the above...is it possible to achieve more...

While we do get reports back of fuel economy gains, that is something we can not guarantee as there are just too many variables that can affect an RV's fuel economy. I wish we could say for sure that you will be able to see a nice gain but we try not to over-promise on that. It would be a good idea to re-tune for the Banks and injection systems.

My 98 GMC K2500 L29 7.4 litre has 2.5" true dual exhaust with pro Flowmax mufflers an X-Pipe, cat delete but still has both upstream and both downstream o2 sensors. At times I get a dtc for bank 1 and 2 too rich. Probably cause no cats.

Truck has an Air Aid cold air induction, throttle body spacer, performance ignition wires with stock gm spark plugs. Truck has 3.73 axle ratios and a 4L80E trans, LT265/75R 16" tires. Stock tire would be LT245/75R 16". I tow a 8500lb 5th wheel in the BC mountains. I would like my speedometer calibrated and better power and torque. What is the best tune for my truck. Can the dtc for bank 1&2 too rich be modified to not trigger the code. What gains will I notice with your product? How much of the torque management system is modified? I would like the speed limiter increase as its set at 160kph from factory. Its a brand new L29 454 from GM. Approx 32000km I installed 3 years ago. 196000km on rest of the truck.

We can accommodate your requests for the oxygen sensors, speedometer adjustment and increased HP/TQ. You can expect about 40-45 horsepower and 45-50 lb-ft torque increase with much better throttle response, crisp shifts and there is a reduction in the "TQ Management".
