tuning

Dyno Time!

I've been looking into rk tunes. has anyone ever done one? they are common with e36 BMW's and are known for crazy horsepower and used to shoot flames. though I don't know about z3's using them. if i posted this in the wrong place please let me know.

hey guys, im going to purchase an M50 intake manifold (common mod on M52 engines) and a dinan high flow throttle body. i have a cold air intake and was wondering what i should get tuning wise. do i need more gas because im going to get more air. someone please help or send me a link or somthing...

i know that this is a place for new members but i didnt know where to post. i am looking for some software (preferably flash) to tune my 97 2.8 Z3. Could somebody help me find a place or find a thread to post on. thanks and have a good one
