If so, is there alot of performance gain and what do you reckon of it?

Here is the info from AWE

+40hp +55 ft/lbs of torque for the 225hp motor New X-Chip

It's actually back to stock chip (with a few intake and IC mods) because I took it in to service mid year last but I've been lazy to put it back since it only gets driven on warm days (roadster), but instantly you can feel the difference of stock.

I also have the APR EMCS which I already forgot the codes for, so I haven't been running their program. One of these days, I'll have it reset and install a race program on it just for fun.

I can't remember correctly but I think the MTM chip takes the stock 225hp, ~200lb-ft to something around 255, 268lb-ft. The + ~60lb-ft is the very noticeable part in acceleration. Lag doesn't change though. Maybe slightly less to stock torque levels, but is more pronounced with a higher torque peak. I have a 2001 btw.

Draw back is $1200+ for ECU with the chip, but it was a purchase I did one time without the need for calibration and new software. On the downside, getting other chips may allow me to maximize performance based on climate and fuel here, which is why eventually I'll play with other programs
