so i was tuned with a tbe and intake/uicp. ive just added a licp, manifold and o2 housing. now i am seeing 10's on spool up (somtimes low 10's) and then low 11s to redline. I was thinking that these mods would have made me leaner? am i wrong? I know that i need a retune, im just making sure everything is doing what its supposed to. I was under the impression that afr would go leaner with those mods, now there really rich so i thought maybe something was a little off. Any input would be appreiciated. thanks guys

 

Would be a good assumption, more air flow leaner...however, you may be hitting different load cells now...re-tune.

 

I did a new IC, piping, instake, o2 housing, etc etc, AFR's went to 10.0-10.3, get a retune, fixes it right up. Thanks Slide

 

more airflow - more load - untuned map portion - rich or lean. whichever. retune it.

 

thanks guys. so it can go either way then, no way to really tell. i knew id have to retune, and im trying to get Al down to tune it.
