Whats the thought on these 2.8 upper pulley numbers

[4.6modular]

My mods are 2.8 upper, Steg. stage III port, JLT 12. inch CAI, Prochamber midpipe, Borla CB, Gords HE, LFP intercooler tank, and a custom tune. No ice on the first pull. Car was strapped down and dynoed after a 1.5 our drive, so no cool down was done.

The last and forth pull was after a 15 minute cool down, a fan on the motor, and ice in the intercooler tank.

I think you are tuned too lean. I have about 11.8 right across to 6,500.

what was your timing?

My prelim tune with a Borla stinger CB, stock H pipe, pegging MAF, 2.8, Steg st 3, JLT CAI, and Raptor SCT was 468 on 91 octane at 17*. On 93 octane and 18* it was what my sig shows. Now I have a MAC 3" and cat less X-pipe, so hopefully it is better, but I haven't had good enough weather to get it re-tuned. Hopefully 500-510. I do know it was enough to pull my buddies 2000 Lingenfelter 408 C5 vert that made 483 at the tires.

My A/F ratio is supposed to be 11.8 commanded and 23 degrees on 93 octane. I know the A/F is a little lean and I am working with my tuner to tweak the A/F to a flat 11.8 throughout. The car was dynoed was on an 86 degree day which isn't bad.

466/487 here on NO port in HOT texas weather. 20* timing with a/f low of 11.3 and high of 11.8

I think you should be shooting for 500...take it to a shop that can tune.
