Hello everyone,
I am new to tuning with hptuners I am currently working on a 408 with LS3 heads , holley Hi-ram , 50lb injectors and LS3 TB I keep getting p1518 and p1515 I run it for a bit and it pops up again and I cant use the throttle. I do have the xlink harness as well. I am having a lot of troubles trying to tune this thing. Any advise would help. Thank you.
Post Tune Log and config you are using.
I know the tune isn't the best I just got it running but this TB issue is killing me.
Thank you
That's reduced engine power that you're going into. I've never had any luck using LS3/7 throttle bodies (identified by the gold blade ), but have always been able to use the LS2 throttle bodies without issue which have the silver blade. PM coming your way.

golden throttle blade TB will NOT work with PCM earlier then 2008. They open into the opposite direction and screw up TAC module. You have to use a silver blade TB from a LS2 or early LS7. been there - done that
