Please define the term "tune" as used here. Im thinking a programer or ?? When my 09 SRT8 gets here in a few months or by spring, I am going to do a Mopar CAI for sure and by then the situation with headers and exhaust should be a little clearer. I wonder how a larger throttle body would affect this situation. Im not really interested in going into the engine,, just bolt ons that can be undone. Id like another 40-50 HP if possible. At least enough to take a GT500 easily. Since its close now that should put it over the top.
Now about those Roush Mustangs,,,
