Black6spdZ:
TeamZR1 makes a great point. For the mail order tune to be good, you got to be able to make several data log files, one at idle, one or two at part throotle while trying to 'visit' as many FTCs as possible, and one or two at WOT. If you decide on another mail order tune, have recent data log files ready and make sure the mail order tuner likes at log files in order to make your tune.

If you go get a dyno tune, check and see if the place does any part throotle tuning before doing the WOT tuning. If done correctly and well done, I think that it may take awhile on the dyno, not just two pulls, but several. But, then, I dont have any experience doing dyno tunes.

The bottom line is that you got to have your own data logger. I use mine alot, you got to have one to know whats going on with your engine.

 

If you go somewhere that doesnt' take the car out on the road before they dyno tune it than you should second guess the job being done.
