My buddy has on 01 225Q, mine is an 02. I don't know if that makes a difference, but... He has the APR 93, and I have the InMotion at 93. We cannot tell a difference. But I have an extra $250 to put towards my exhaust. Also, the INMotion comes with a 100% satisfaction guarantee. If you don't like it, send it back, they set it back to factory, and you get $250 back in your pocket.

 

Ive got the REVO software and seems to be pretty good. I definitely noticed a difference considering the only mods so far are that and a forge dv.. cost me about 500 for the software but it will get tuned for free too by the shop if need be.

It sounds like you cannot go wrong with any of the chip tuners listed.

 

i think ive made up my mind, but i saw a Revo SPS2.. what is the difference in the chipping and that ?

 

The SPS devices (3 of them) let you swap between programs and change psi and timing (0-9) and are used WITH a revo chip, not instead of one.
