Just got my car tuned @ EIP Racing, San Jose CA. Big thanks to Paul @ EIP. The 2.5hr drive from Sacramento was worth it (except all the cops with laser guns).
My base dyno has the following power mods:
- K&N drop-in filter
- Motordyne 5/16" spacer
- Ultimate Racing High Flow Cats
- Borla TD exhaust + magnaflow x-pipe
- 4.08 gears
Question: I asked Paul this same question and he said that the DynoJet equivalent is 25%. I doubt that so if anyone has dyno'd both DJ and Mustang, let me know your results.
Edit: I forgot to mention that my buddy came with me to have his M3 dyno'd after my tune. He's got Shark software + Rogue Engineering w/open valve switch exhaust. He made about the same torque as I did but his HP was 260!
