On an otherwise stock 170HP Duratec maybe 10 HP/TQ at the wheels.
Add another 5/5 for a Y-pipe. Top it off with a chip (higher redline and decent gains on the stock PCM using 92 octane fuel)

Those 3 will get you pretty close. (maybe 190-195 crank)

Well provided it's a MTX. If it's a slushbox you have no chance to ever make it very fast!
