I just put on a boost controller on my stock turbo. I have all my EM, APS front mout intercooler, aps intake, perrin up and down pipe, and a perrin catback. thats all the mods I have as far as the engine.
It was only boosting at .8 originally and thats why I put in the boost controller. When I turned up the boost controller I dropped to .7. I dont know what happened!!!
