I love mine. 
I havn't been able to get it to the track yet but SOTP, and the fact that my nittos won't stick AT ALL in first gear now, leads me to beieve it will perform alright. It lopes HARD too. 
Edit: Referring to MS3

I am spraying 150hp so I don't want to gear it too low. When the 10bolt grenades I will do a 12bolt with 3.73s but I am gonna sport the 10bolt until it pops.
So the TSP 231/237 is a good choice for all around power? You think it will break 400hp with this cam with the usual bolt ons? What about valve train noise? is it really bad? Do I need different push rods? I want 400hp with stock heads and good driveability. Then spray the 150 on top of that. Should be sweet!

I dynoed 381 rwhp to the rear wheels with mine, through a 12 bolt with 4.11 gears, a much heavier driveshaft, 17" wheels (instead of my stock 16"), and through cats. Without cats, and with a 10 bolt & stock driveshaft, I'm pretty sure I would have been up over 400 rwhp pretty easily.

Typically a "nitrous friendly" cam has a large exhaust bias. Either the 231/237 or the magic still would be considered good nitrous cams. IMO there are better cams than the 231/237 from TSP. For a LONG time that is what I was going to get, but then they came out with several new grinds, which grabbed my attention.

Jason at TSP even recommended the Magic Stick over the 231/237. he said the lobes were "softer" on the 231/237. Not sure what he ment but he strongly recommended the Magic stick for stock heads over anything else he had to sell so...
softer lobes = a less aggressive ramp rate...it lifts on the springs slowly and evenly and is not a harsh fast ramp rate...typically the harder the ramp rate the more power but more wear on springs...like the tsp231/237 cam will not need new valvesprings for a long time...however the ms3 you will have to replace the springs in probably half the time...

I don't drive the car daily so...it will be a few years before I should have to change springs assuming I get 20k out of them. The car is a 99 with 27k so.. Does that quick ramp rate contribute to making power relatively early in the power band CONSIDERING the size of this cam? I was told at 3k rpms it would match a stock 99's cam torque. Sales BS? They did tell me it would be much better under 3k rpms IF I had 4.10s so that leads me to believe its dead under 3k.

It's totally possible for a big cam to make stock, or better than stock, torque than the stock cam at 3k. Yes, a higher ramp rate equates to more low end for a given duration, etc. The valves are open further sooner with the harder lobes. The 231/237 has a pretty mild lobe compared to what else is out there nowadays. The MS3, on the other hand, is pretty harsh. A lot of the reason larger cams feel weak down low is because they take off so much at high rpm that, relative to the upper powerband, the low-mid range feels soft. That fact makes it sometimes seem a lot worse than it really is. That's one of the great things about an aftermarket converter for the A4's....we don't have to worry one bit what kind of power a cam makes at 3k RPM cause it'll never see 3k at WOT.
