Just installed a Whipple 2.9L kit and cannot get it dyno tuned do to ETC service error over 3/4 throttle. Base tune has been established with updated injector data and it idles and drives fine up to 3/4 thrrotle. One you go wide open service ETC flashes on dash and goes into limp mode. Simply pull over turn off and turn truck back on and it will drive fine again.
Has a barometric too low code but believe that is a diagnostic code voltage update to fix that from research here.
Sometime on start it gets the ETC service code, but again just restart and it goes away.
Any idea on what to look for. Tried replacing and relearn on throttle body but it didn't fix it.
Any help greatly appreciated cannot finish getting the truck tuned till the issue is resolved.
