I'm right there with you. No tuner will give straight answers about their tune so how can you believe what they state?

 

Didn't Brutal say the stock tune is good for plenty more power? If so, I'd be inclined to leave it be.

 

X2!!!

 

so are you guys seeing that the afr is staying at 11.0-11.5 at wot on the top end? I thought they got a bit rich up there?

I haven't run mine on the auto enginuity software yet so I have no real world experience.... yet.

 

that is a bit rich, optimal AFR for forced induction is 12.5:1

 

What' I'm asking is what afr is the stock tune at during wot on the upper end. I know most of the factory tuned supercharged cars are super rich at wot as a safety measure. I'm installing alky injection so I'd be fine with 12.0-12.5 if I had it tuned. I've heard of factory tuned cars being in the high 10's at wot.

 

I will check for you today and post up
