So I am putting a procharger p1 on my car I have had a couple people tell me that my car will be ok with the ms3 in it rather then changing it to a blower cam. So hears the deal, I got my balancer (underdrive) off today to put my stock balancer back on and pin the crank and noticed I need to change my water pump because its leaking so should I change my ms3 for a blower cam since its not that much more work just to change it? My mods are afr heads, full exhaust, fast 90/90, ms3 cam. If you guys think I should change it, what do you recommended?

It will work and it will make awsome power, the only real benefit to going to a "blower cam" would be to get something with less lift for less wear on the valvetrain but other than that its up to you on weather you want something milder.
You will be fine with the MS3. My MS4 made great numbers. If there is something else you could improve with the money you would spend on the new cam, then stick with the MS3.
Interesting to hear. Ive got a MS3 on a 113LSA, i was planning on dumping it indefinately, but this is a different take.
I would have thought the long duration and short LSA would make the cam less friendly in a boosted environment.
Well aware it will work, but for power production, figured a different cam would build better power.
Only other thing i might look into swapping out is your FAST intake. Ive heard of alot of them cracking under boost. Theirs only 3 bolts at each end of the intake holding it down. It relies on vacuum to assist in sealing it.
Of course you'll be bleeding off a lot of boost, considering the MS3 is a top end cam. That's not my opinion. That's a fact. Look at the valve events. Will it work? Sure. Would you make more power with something with less overlap? Yup.

Do you feel then the MS3 (113LSA in my case) may work well with a P1?
I dont have a problem swapping the cam out, but ive got a MS3 here, and if were talking minimal HP gain for buying a new cam, i might as well hold onto it.
So Arun, that's stock cubes on a car that the typical board member would be driving? Looks to me like a car with expensive heads, intake, etc. Not the typical car on here. And with the OP not specifying, that is the route we have to assume is relevant.
Even looking at it, you can tell it was in boost from very early on (or it's not stock cubes) and was comparatively weaker down low compared to once it took off.
Thanks for everybody's input My ms3 is on a 113lsa so it looks like I will try it out and I hope it will do good. I will keep you guys posted with the #'s when I get the car done and tuned. I think im going to trailer it to cms to get it tuned, I was never satisfied with my tune I have on my car now, you would think after 3 times of taking it back they would have been able to fix the surging problems and whenever I would turn the a/c on the idle would raise to 1500 rpm and hang there lol

I did also hear that, but I was told I would be alright being under 10 psi and im looking to be about 7-10 psi, I was originally thinking about going with a sheet metal intake until I saw the $2000 price tag . I was also thinking about the Warrior one piece intake made by weiand, has anyone else heard anything on this intake? There gains are better then the fast so they claim .

If it makes power on the motor it will make more power with boost.
For example-take a stock motor-but in a G5X3 and add 8 psi, then take another stock motor and stick in the popular 224 228 114 cam and add 8 psi. The bigger cam will always make power-it may make a bit less down low-say up to 2500 but after that it will take over.
There will always be a better cams for the combo but honestly adding boost will always make more power. I just think there are so many other things you can spend the $500 or so dollars you would spend on a cam and the re and re.
I mean put that money towards a 8 rib or meth kit or guages? The only time I would suggest swapping cams is if say for example you put in a big nasty N/A grind and you want something mellower this time out.
