I have a 17 auto gt with the roush 670 kit only other power mod is a mbrp race catback which I doubt did much. Seen youtube vids of making 10whp with the cai lid open but I actually lost 5whp doing that. Very happy with the numbers, roush tune runs hard.

Nice power with hardly any boost. My car needed 25 lbs of boost to make those numbers, LOL.
Exactly what I thought as well.
I was like,.....less than 8lbs. of boost?!?! :eek:

Thanks and Yes, stock kit down to the filter. I looked at the logs and a/f, timing, and duty cycle all looked really good. Kind of reminds me of a vmp tune exept with a lower Rev limiter. Kept adding timing with no knock detection.

Makes me want to spend some money. Congratulations. It's been 12 years since I last drove my 03 Cobra, so I think it's about time for another 500+HP car in the garage.
