Well, i took my car to the dyno today at Thompson Motorsports. It has a Spintech Cat-Back ,and a K&N CAI. It made 385/381 first pull, and 396/393 2nd pull. Car is still on the stock tune, maybe i can worm out another 4 with a tune for a 400 RWHP car..... Dyno sheet will follow

Get some miles on it so it can break in and loosen up. I just had my 2010 with just a skoosh under 26K on the clock made 410HP/413TQ on a Mustang Dyno 5/11/12. Granted that's in Tampa where it is only about 20 feet above see level.

A tune will put you over the 400 mark. It will make it a completely different car through the throttle range. There is quite a bit of torque management in the car from GM. And thank you for coming by for our dyno day.

The different results between pull 1 and 2 are interesting. If nothing was changed, that is a larger variance than I am used to seeing between two back to back pulls with no changes to the tune.

Guessing the car either needed to warm up or cool down and you did one or the other in between those pulls? Guessing IAT's or coolant/oil temps were different.

Headers and tune will put you solidly over 400 on both sides, and change the personality of the car with no downside. The tune alone will smooth out a lot of the torque management, as mentioned.

Those are good numbers as we speak, i do agree with above should be fairly easy getting you past 400rwhp with just a tune or for tune and LT's.

Nice numbers, a tune will really wake it up.
