Save your money and get it tuned by Simon. I used West Racing (albeit a while ago) to tune my ED XR6 after I had a Crow cam fitted and when I got it back it idled at 2500rpm, pinged its head off under part throttle, and failed to run in closed loop. When I asked him to fix it he said that "Sorry we tried, but this is the best we can get it" I dont think so Tim!!! I took it to another tuner and all my issues were sorted in 20 minutes!!! I subsequently called him up to let him know that another tuner had fixed my tune, and he told me on the phone that "No, that's not possible, he can't have, blah blah blah" I don't have time for such arrogance. I wouldn't touch West Racing with a 10 foot pole - and as Ben said, they are expensive. He may be good with WRX's but he sure isn't with Falcons!! Take a look in his workshop after all! It's full of Commodores and Subarus! Maybe he has upped his game with the BA.. I sure hope so... but still, I personally would not use them. Cheers, Ross
