SEll that BOV it SUCKSSSSSS!!! I have one too and it is horrible just search around youll know why. With that said I wouldnt even set the boost higher than 17-18 cause I had the same setup and my car whould hit fuel cut left and right.

 

Tell me how you really feel lol.well thats good to know.so which one do you like i dont care about the noise or how loud i just want a good one.

 

I have now the APS duel vent which I only got because everywhere I read it seems to have the best drivablity with the Evo (I havent tried as my car is storred) The only negitive to that aps valve is supposed to be that it leaks after 26PSI at the vac nipple, but they have little fixes for that too so it can hold 30-32PSI

 

So with that bov 20PSI no prob and then anything higher were talkin fuel pump and all those goodies.

 

well with any BOV 20PSI is fine..... except the HKS cause it just sucks on MAF cars

 

buy a rbov that would be better it then the hks, they have good parts setting aside the bov, but yea i have an 03 evo i have my boost set at about 19-20 some days ill boost 21 if its really cold out side, but yea dont go passed 20- at least try not to.

 

you do can do what other people do and buy a fuel pressure regulator and turn up the fuel but i wouldnt advise it just get the fuel system upgraded and do it right, and it makes you and the car feel better about racing.

 

unless emonz says somthing dont do it i just dont think its a smart thing to do

 

Get one of those new recirculateable Tial BOV's.... if they are out yet

 

they should be out by now
