So i bought a manual boost controller off of ebay. And i spike to like 25 pounds. Then it just hold at 14 pounds and decreases as i get to red line. Is that ok that i bought an ebay Boost controller. or should i just go buy a $300 electronic boost controller. And should my boost be doing that. Should i buy a better wastegate?

 

thats way to much for the stock fuel system to spike that. and yes you need a better wga! the stock one is **** and only has a 4 pound spring in it! If you buy wga and set it to peak at 17-18 psi and hold 14-15 that would be good. but i am not a pro but that seems way to much to me on the stock fuel system.

 

really just buying a boost C is not going to help that much cause you have the stock wg!

 

the stock wga has a 7lb spring, not 4.
