this may belong in the tuning forum so move it if necessary. the truck's PCM thinks it is still running my old bolt-on LM7. currently there is a LQ4 and GT2-3 cam in the truck. the truck runs the same in most conditions as it did when i first installed the new motor but i've notice it is no longer shifting at 6k rpm like it used to. instead it shifts at 5.5k and it has felt quite a bit more sluggish at WOT. this is recent, it didn't behave this way after installation. i just though it was weird and wondered if this was the PCM overreacting to the new inputs its getting or this is an indication of a problem. no CEL or any other problems noted. i'm waiting for the tune to arrive.

 

Damn I'd be scared to take it WOT without a tune. What injectors are you running?

 

stock injectors. on the datalog it showed it was running rich. 14:1 cruise and 10.9-12:1 under throttle. i wasn't told what the duty cycle was.
