Hi Danny, look on a site called Quontum tuning, they do all kinds of maps and they guarantee an big increase in noticable power, iam having mine done shortly and will post the results on the forum, you should definitely notice an increase of 98 lbs of torque and 45 bhp, if you talk to a good tuner they tell you to be very careful ; some garages are not always honest with the work they do , if you know what I mean, as iam sure you do, I would take ricks advice have it on a rolling road to check the results, mick.
