yes msp is rated at 170hp and about the same in torque, msp are known for their midrange, 3500-5000rpm, power. they are good on launch and through 3rd. any higher speeds than 80 they fall off. this is due to the variable intake vanes in the runners. i had to take mine out and i dropped .5 in the quarter and my ending speed was 5mph faster. another advantage the msp has is a limited slip,its crap but it works to control anything less than 300hp. for the mp3 the best thing to do is to get a small squirt of nitrous. they have the same motor as the msp so its very limited, i would say a 50 shot and nothing more. or just get a disco potato and throw 7psi at it. just my two cents, this is all assuming that you have some disposable income. remember, pay your mortgage first damnit.
