How much power do you plan to make?

[metalmaker12]

from my travels a stock sti will read 215-235whp on a mustang dyno and 245-255whp on a dyno jet. I been told the mustang dyno is calibrated differently, but can be corrected to read the same, but is not considered a proper hp measurement by the company.I have gotten many cars tuned on both setups and the Mustang dynos always read lower if there set up the way they are supposed to.

PS: Thorne,I might have been a little off before on the differences, but it is 20-30whp on my cars has been the average
