Guys, I have an rb25det S2 in my S14.

Mods;

Fleabay FMIC550cc injectorsPower FC and Datalogit, zeitronix widebandt3/t04e 60 trim .63 ar stage three wheels (super common turbo)3" exhaust including DPTial wastegate

I think thats all the important stuff.

My buddy and I started the tuning process yesterday. There is a local company with a Mustang Dyno who are a bunch of great guys. Very nice, and helpful and reasonable with prices.

We spent most time on driveability stuff, and part throttle. It drives freaking great now on the street.

Only had time to tune my maps at 5psi of boost. They closed early.

252 hp at the wheels and like 225 tq at 5psi.

Sorry I do not have any graphs, but I forgot to take them with me.

Later fellas - Evan

Yeah its definitely a good start.

Like I said, driveability is much better too.

My freind is not a professional tuner, but does have quite a bit of experience. Hardest part for him was learnng the datalogit software honestly.

Thanks for the encouragement guys.
