based upon my mods do you think i should get a n75 j valve on my car? If I do will i really notice the difference? right now i peak at about 19-20 psi on my giac chip and it drops to about 15-16 psi but sometimes when i redline 3rd or 4th gear to stock redline the chip disengages and everything goes back to stock feel and my boost drops down to max of about 8 psi. I dont know what to do in this situation... I have to just restart my car. Will the n75 j valve fix that?

 

Doubt it will. Sounds like your car is going into overboost.

 

No it wont, like david9999 said, it sounds like your car is overboosting already. So why would running a couple more pounds on top of that help? Save up and go with a fmic. You are way out of the efficiency of the ko3 at 20 psi, so you are just blowing hot air.

 

a FMIC would be good and you will get more HP and see a difference and be able to maintain your boost way better

 

WOW 19-20 with just a chip. I thought it was only supposed to be 17 max. Well anyways the n75j valve made a 1.5psi change in my B6. I boost to about 18.5-19 and hold 12psi to redline. I really noticed a difference in power so I would highly suggest you get one after you figure out what is going on with the overboosting.
