I have ARC intake pipe, ARC air box, Greddy exhaust and HKS bolw off in my evo x. Does someone know can I use COBB AccessPORT? Which map I should downloard?
THX~~~~~~~~~~~

 

Replace the HKS BOV with the stock, and use the Stage I + HKS map. (unless you have a downpipe and HFC on your exhaust, in which case you should remove the boost pill - still replacing the BOV - and use the stage II w/ HKS map)

 

^+1, get rid of the HKS, unless your raising the boost the stock one should do just fine.

 

But what if I want that cool shwoomp woosh sound?!

 

I have a greddy downpipe~~~~ Is that ok?

 

I can get rid of the HKS blow off, should change to other blow off or just use original one?

I had come through 3 times engine just like shut down on highway when I over 130km/h more than 1 hour or 160km/h 30mins. Than I have to cool down the car than restart, but will show check engine light. Have you seen this problem?

 

Get O2 wideband for safety!
