I have a highly modified 2006 chevy trailblazer with the I6. Most recently got my build on the road with lots of upgrades and realized I"m running out of fuel with the 60's and e85 at around 4300rpm. I need some help with the easiest way to get the appropriate ifr.
I've seen a lot of comments for the other ECM's that say halve the IVT term tables....we don't have those.
So question is...what else needs to be changed to use this method. I'd rather not scale the whole tune for airflow, fuel and torque. Can anyone provide assistance?
