What a few simple mods and a tune can do.

Going kaboom, when the weather is different from the time it was tuned - priceless.

That's not how EFI works...


This isn't some old carbed vehicle you have to retune every time the seasons change...

Does not matter. Very few tuners bother adjusting weather compensation tables to your particular car, since that requires a lot more work. And whatever ends up in those tables is usually some 'ballpark' junk that _will_ knock under conditions where stock tune won't.

The difference between a good tuner and a crap tuner... Stock tune also caused DI injector seal failure.

Good tuners work for race teams/OEMs and are out of the price range for a typical consumer. The rest are amateurs that aren't worth the $$$ IMO.

My advice to anyone changing the tune - learn how to adjust your tune yourself, log like crazy, and examine your logs often. No tuner will do that for you.

Dumb question.

I really want to get an exhaust and a tune that would get the best out of the existing setup. Would either of these mods mean I would void my warranty? I'll be going catback, so I don't think that should be a problem. A tune would definitely void it, but what if I 'flash' the old tune back on the vehicle whenever I have to take it back to the dealer? Does it work that way?
