So a little update, since its 3am and I am still awake I decided to update this thread a little since there were some mistakes I made from my previous update.
FIRST OFF (thank you The_Silencer for your gun doc work) I cannot thank you enough Linh.
You pretty much took a beat up gun and made it into gold (Systema worthy).
He's done so much awesome miracle work on my gun, I find it hard to believe this thing had every single problem in the book only a couple months ago.
My P90 is still going strong. I think its 3 years old now.
That is pretty much it looks like currently.
For the most part there are no stock parts in it anymore and it is hitting a nice consistent 335FPS with a very nice trigger response.
Finally bought a P90 Dump Pouch from thevestguy for $80ish bucks (on sale $5 off I think) and FINALLY got around to buying a Lipo (well I bought one before, tried putting deans on it and killed it so I bought a replacement with an adapter)
Overall I am still satisfied with my P90. Its the only gun I own and I plan on keeping it that way, well at least as a primary.
If you are in the market for a P90 currently, I suggest you hit up the AV retailer section and classifieds. Since I got my P90, prices for them have dropped drastically and TM P90's are popping up left and right 
On top of that there are new P90's so get that Visa out and prepare to start swiping.
MY ADVICE: BUY BUY BUY
