Dynoed yesterday, not happy Here is my info-
99 A4 58k miles
Stock block and heads- Dynoed in 3rd gear locked. Dynojet.
MTI R1 cam - 232/236 .575/.578 114
918's
SLP LT's and ORY
SLP dual/dual
Lid/bellows
LS6 intake
Ported TB
FTRA (obviously makes no difference on the dyno)
Cutout (right before the axle)
Tune
It only did 320 with the cutout closed, 330 open. Peaked about 5500 also, I was figuring with this cam it should peak at 6000 or better. They did say that hteir dyno usually shows about 15hp less than others in the area on average, but even that would be somewhat low. I was thinking it would do 350ish through the exhaust. A/F ratio was at about 12.9 and the timing was tried at 25 and 28. We made 6 pulls all together, no real gains were made. No oil on the plugs, car wasnt leaning out at all. The car was sprayed on before I owned it and I wasnt told until I saw the wiring had been taped into. It seems like the motor is okay, but I think I may do a leakdown and compression anyway. Probably check the valvetrain also. Looking for opinions.

What kind of plugs does the car has ??
i'd check the plugs then the Valvetrain or maybe there's a leakage somewhere cause it seems pretty low number for a Cammed LS1 & full bolt-ons..seriously the car should be scanned !!!
Keep us posted anyway & good luck .

LS6. I am going to have a closer look at the fuel system and valvetrain. It wasnt leaning out, but I wonder if just a couple of cylinders have clogged injectors.
