spell your words right! your not a chav are you? da?? well when you say different? what do you mean by that? slow sluggish? have you tuned it or put new injectors and fpr in? that may help also a new walbro 255 fuel pump? if you have not done these things then look into them as that might be your problem. but explain DIFFERENT to us maybe we can help more!

You do realize EvoIII's are not DSMs right? Granted, they have virtually the same engine with slight differences, but the ECU is on another level with all that JDM shiznit. Have you tried asking on the EVOI, II, and III forums?

What the hell are you running at 47psi of fuel presure for?! And what engine management are you using?

Posting up a log will tell us more than you ever could.

10-10.9 AFR is a fairly wide range, 10's are kinda rich. Static 10` timing? What's up with that? Are you sure you don't mean base timing @ 10`? Usually people set their base fuel pressure at 43 which is basically a standard.

Do you have a logger? We need more information and a log would help. Do you know anything about tuning and working on the car or did you just buy it this way?
