so I got my car tuned today by zzperformance... I had to change from the 2.5 to a 2.9 for them to want to tune it. I got 250 hp and 220 torque. Im running around 11.7 to 1 af ratio at wide open throttle.

good numbers for a 2.9 why wouldnt they at least do a 2.7-2.8

Too ******* rich. That was with 60's as well? What the hell are they doing?

redwingsfan91086

that isnt too rich considering I was getting soo much knock retard any leaner than that. I wasn't even getting any more power leaner anyway...They kind of didn't want me to go any smaller of a pulley since it wasn't worth blowing my engine etc. so I just did the 2.9 since Im selling the car and it really isn't that big of a deal

11.7 is a bit lean, but not bad at all. i like 11.5s

redwingsfan91086

eh It's somewhat lean. For the amount of boost and the af ratio its about as far as you want to go unless you want to blow **** up lol

What the **** were you doing with a 2.5 on there?

theneelster

He's riding the bull!

Isn't there a guy on here tuned for completely stoich at wot (14.7) without any problems?

lewisb13

No.

rrutter81

eh its not recommended

i think area claimed high 13s with his flow...but most people dont have headwork, cams, and other little goodies.
