18psi 255whp/251tq
Unfortunately this set-up came with a 7psi internal wastegate spring. The manual boost controller could not hold stable pressure as you will see referenced in the orange line. Boost would peak at 18psi(3600rpm) and fall to 14psi by redline. This resulted in what we calculate a 25-30whp loss up top. We estimate at 18psi this set-up should make 280-285whp on a mustang dyno. This particular mustang dyno reads 10-15% lower than most AWD dyno’s do.
