this wasnt my car dynoing but my buddy has a 95 trans am with a flowmaster catback K&N cold air and pcmforless (he learns from the best) and i saw him put down 265 RWHP 298RWTQ but his a/f was 17.1 at idle and 15.1 all the way to 18.1 at WOT, is this normal for a pcmforless tune?

 

That is in no way normal and would indicate a dangerously lean condition if those readings are correct. If they are correct I would suspect some other problem. BTW my experience with PCMForless has been that they usually err on the side of caution, ie. a tune that is slightly rich.

 

i have always heard theyt tune lean but i didnt know this lean

 

they deffinatly tune on the side of rich. I dont think they would be in much bussiness if they handed out tunes that lean often.

 

could those readings be off? those seem like good numebrs for such a catawompus A/F ratio
