So I just dynoed stock at 218whp and 190wtq. Which is more than I expected. it was on a dynojet.

But what kinda scared me was my a/f readings. Started at 14 or a little higher and the lowest it ever dropped was to 11.9 . Most runs it only dropped to 12.2 or so. Now I come from a talon TSi and safe A/F readings for it were always around 11.1 or 11.2.


My question is: Is this safe? Is this normal? What should I tune it for when I go to my 2.7" pulley and larger injectors?

 

mid-high 11's low 12's

 

and if its stock dont worry it blows dealerships problem

 

Problem is its not gonna stay stock for too much longer.....

 

I understand that

I would suggest a 2.8 with 42.5lbers with from intense if your on a budget you can get a MAF-T to tune with, or the better option in HP Tuner intense can send you a complete pcm for a decent cost

They will tune it for ya man, they are pretty decent at what they do and have dynoed alot of LSJ's

F.Y.I the 60lb 2.6 is pretty risky now adays alot of people are running it fine but with temps dropping its seeming to be a problem in my opinion i would wait for 60lbs till spring

I already blew my motor so im gonna figure them out

 

Actually, I'm going with a 2.7" pulley and 42.5# injectors. Remember I'm in ALbuquerque @ 5600' above sea level, so the smaller injectors should be fine. I'm being tuned by a local tuner in town with HPTuners, and they are gonna use the boost bleed to limit it at 18lbs. So that should be fine.

Thx for the input, anyone else have anything to add?

 

where are you getting these AFR #s because if its off a tail pipe sniffer its about a accurate as sticking your thumb in the wind

 

Lithium just so you know bdwarr6 just blew up his engine.

 

trust me get a wideband and look for low 11's to low 12's that is the money range to keeping your motor
