I Have just used a TTS tuner in place of the stealer supplied SERT and i have come to the conclusion that the stealer had not tuned my bike at all since i had aftermarket air intake and pipes installed 18 mths ago.

I have also come to the conclusion that if you want a good job done, have a go yourself take it to them as a last resort they wont be getting any more of my money.

I know its been said add norseum on this site but ill say it again TTS is a great product
