It sounds like you should talk your tuner into buying the Banish DVD???? or both of you could go together on it!! Otherwise you could check out and post your Tune/Scan files on the HPtuners Forum and see if someone there could help you. As many have said it could be a number of problems and sometimes when things like this arrive its better to get a full grasp on the Software/Setup/Tabels etc... and just start all *new* with the tune. You can always save your current tune and can reload it if you run short on tuning time. But slowly work on a Brand new file to see if the problems start to clear up. Start with idle, then move to Partial Throttle/Cruising, and finally the WOT part of the car. Taking your time until you are happy/satisfied with your results.
