QUOTE=Rubrignitz;6355689]Personally I would NEVER trust a mail order tune. I never realized how bad they were until I installed cams. All the mail order guys told me to hit the road at that point. I don't blame them. How can you properly tune a car w/o seeing the results throughout the powerband???

All these guys w/ mailorder tunes getting spanked by cars w/ dyno tunes doesn't surprise me.

Yep, I'm with Rubrignitz here......!
