Because every engine is different its hard to say... plus we were working on a very small amount of time with a few limiting factors:
1. It was on a Mustang Dyno so the numbers are usually a little lower than on most other dynos.
2. I have an xi so I lose close to 20% of power between the crank and the wheels... a rwd bmw will only lose about 8-10% normally.
3. I have a burnt up clutch so I don't think they ran it as hard as they could've nor got as clean of a pull as they would have liked to.

With all of that being said, I think its best not to put up an actual number right now but I promise I will very soon... I don't want to over/under estimate just to be fair to Tony and LETMotorsports and also to anyone who might want this tune so they don't expect more than they can actually do.

I can tell you however that they are aiming to get about 10-15hp (about the same in torque) out of these tunes and after driving 150 miles with it on the car, I have noticed a significant difference in the mid range pull, mostly in 3rd and 4th gear. With a little bit of tweaking and a new clutch I think this car will be up there with a stock 330i if not quicker.

I don't know about the price because I think they are still working that out right now but I would assume somewhere around the $400-800 range would be a fair estimate.
