Which should I get ecutek stg 1 or stg 2?
 

I have a front pipe mid pipe and dual exhaust with dual mufflers. Deleted the second catalyctic. I also have an injen intake. I was thinking about getting a stg2

I don't think it will matter. "STG1" handles exhausts about the same as "STG2". And the Intake makes nearly nothing once a tune is applied.

Really!?

Most of the power from the injen intake is created by maf trickery. Once you have a tune that accommodates for that I'd imagine there wouldn't be much of a difference.

Yup. The only reason Injen makes power on a stock tune is because it tricks the MAF into running the car leaner. Once you get a tune, which levels that AFR out to something safe. They all mostly make the same power. The flow of the stock intake isn't a restriction until you're above 195whp NA.

stage 2? I dont think it will matter, because your e-tuner will change the log to tune to your car. Correct?
