First i would say over the past few months i have learned alot on this site. If not for it i would be lost. My 86gn is running great now and this site has helped alot in getting it right. Now i have a new problem. As long as i just drive the car everything is fine. If i go to mash on it the boost wants to go out if site. I have a 62/66 precision and 3 inch dp with external waste gate all purchased from full Throttle. I have the manual valve inside the car and printed the directions off the forum so its plumbed correctly. It doesnt matter which way you adjust the valve there still seems to be no control. Im thinking of purchasing a new control valve as mine maybe bad. Any thoughts? Send the comments
