i recently installed my sr i did the wiring myself everything seems to be working im running stock piping but i have a problem.IM NOT SURE HOW THE VACUUM LINES GO i have it hooked up like this. theres 3 vacuum nipples on the throttle body 2 of them are the same size one is bigger. One of the 2 runs to my wastegate. The other runs 2 my guage. but the bigger one well i dont know were the heck to hook it up. ok so i drive the car and when i punch it my boost gauge shoots up to 12+ and i get fuel cut. starts jerking. im running a t25 with a non- adjustable wastegate can anybody help me plz!!!!!

the bigger one i'm almost positive runs to your cold side piping. i'm guessing it's a red top so that's my uncertainty. i know thats where it hooks up to on the 14 black top. although i'm not very good at this but i don't think that's your problem. for some reason the actuator isn't opening and causing you to boost high. think it might be time to get hks actuator.

right. one big one goes to cold side. if you have stock intercooler piping there's a fitting there and if it's a kit should be one on there too. if not make one. the other 3 go over to the vacuum tank thing. Forget what it's called. I'll go check in a minute on my car just to double check.
