Your tune can be fine tuned after you have both the header and tune installed but as I stated mine has never been datalogged and Randy at FSwerks has adjusted my tunes several times for other things such as increasing the transmission pressure(=

This actually gives me a little anxiety. I've been around hundreds of tuning shops and been around some of the best tuners and honestly no car runs the same with the same mods. No matter how many they have done, all cars run differently. Shift point tunes don't need data logging but tunes for a/f ratio changes (intake/header/exhaust) all require specific tuning if your want your car running 100% . I bet if you data logged and had a tuner check it over there's room for improvement.

Forgot to add, when most tunes are sent out, the tune that comes preloaded is usually just a test tune before datalogging, and probably shouldn't be used in the long run, without precision tweaking for your specific car and the way it runs specifically. just an FYI

yes but while there may be room for improvement it would be such a subtle difference that its irrelevant unless trying to make your track time better by a tiny bit. For a Daily Driver that only sees the street the Settings they have the tunes at is very good

In a way yes, but it helps the car maximize better, in mpg, a/f ratio, not just power

My car runs awesome w/ a Fwerks header/cams & tune. Very very smooth & pulls great.

FINALLY the WAIT is over.

Special thanks to WRC_FAN for helping out during the install !!!!!!

Race Exhaust and Race Header sound good. Don't really think I need a stealth resonator any time soon.

Sounds great for a little bit, a weekend or so. Great your header is installed.
You will later, try taking a 100+ mile trip w/ just the race exhaust. Trust me you'll be ordering at least a stealth muffler, later.

LOL This^
It will be cool and all for a few days then when you get all of the loud ricer looks and try dealing with the resonance down the highway you will want another muffler haha
