1.8, GT2554R, 420CC, 9psi, 220whp (Mustang Dyno)
Car is still at the tuner, so dynosheet to come.
HOWEVER, I am skeptical of these numbers... Don't they sound extremely high for a 2554r at only 9psi, especially on a Mustang dyno (so 240+- dynojet)?
97 1.8 with 60k miles
gt2554r @ 9psi
420cc rx8 injectors
3" turbo back with 3" cat
Colder plugs, IAT, etc etc.
Professionally tuned by a reputable tuner
Apparently my boost control solenoid from DIY is broken, so they could only tune to the wastegate.
