Another new guy question...sorry. Once Stillen exhaust, ztube, and spacer are installed where would I get a tune? Just any old mechanic? Only some of them will do this from calling a couple. What does tuning involve/cost? Dallas shop recommendations or any info are appreciated.

 

I'd recommend getting some high flow cats before you tune, either fast intentions or berk technologies. Go to www.uprev.com for all your answers, if you're going with an Osiris tune. Their main shops are in Austin and Spring, Texas. Don't go to any random shop.

 

+1 HFC or Test Pipes before you tune.

Osiris is probably the best option if you stay NA. Its like $400 + dyno time. Depends on the tuner for cost of the dyno time.

 

Thanks. Will probably hold off given cost/location/etc. Good info though, appreciate it.

When you have the money it's worth every penny. Osiris can tune your car with up to 5 different maps including:
Fuel saver
Race
Valet
Anti-theft
Stock
Etc.
