Default 4.8 turbo

hit the rollers today with what i thought was a bit disappointing. 4.8L turbo at 6psi. FMIC z06 cam. and now i cant get my scans to upload. I ran it in 3rd gear, 2800tc unlocked. 15* of timing and starting IAT of around 102 degrees. It was on a mustang dyno, Netted a best of 360/360. Any one have an email that can perhaps have better luck posting these. thanks..

Those really aren't bad number for a mustang dyno, 15* and that boost level. That would be a bit over 400 on a Dyno jet. The numbers in my sig are the result of a dyno Jet, 11psi, Meth and an aggressive tune. Your probable pretty close to were I'm at in street trim, like right now with just trying to keep my truck alive for the next couple weeks,

I agree, not too bad for a 4.8L on 6 lbs. Did the fuel ratio swing as widely as the sheet shows? The sheet also shows an average of 13.3 which is a bit lean for FI.

OK, cool. The last time my truck was on the dyno I had someone tell me I was lean. Mine was reading something similar in the 13s.
