I just bought this 97 suburban 4wd with the bbc.
My problem is that my old truck was also a 97 Chevy with the 5.7 engine and it feels like the old one had more power.
This engine runs great but with the difference in fuel consumption and lack of power I’m disappointed
Will your tune help or am I missing something?

The tune will definitely wake the truck up. Not sure if you have any other issues causing low power though because it should outperform the 5.7L, especially towing.
If I send in a functional pcm for my Suburban mentioned in last question whats the average turn around for it? Thanks.

We are running about 2-3 days on turnaround right now.
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.

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,
Jared

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.
