There is NOTHING you can do to VTA properly unless you get rid of the maf.


You will always get stalling issues with a BIG intake, me thinks it is cuz the MAF gets misreadings, add fuel down low, or take it away, but on mY DSM and now evo, I never got it to run as stock, but HELL my STOCK evo would sometimes stall like you are describing.

 

I also go the MAF pipe and experiencing the same thing. I was getting close to stalling wiht the stock pipe and the HKS BOV/VTA. Now I can't keep the damn thing running. HAHA I tried to put the 1G BOV in but the stock hose will not reach, fit correctly.

 

Could you tell us what we need to do in order to correc this using the S-AFC? I've got just about all your bolt ons. See sig for mod list.
