what do you have controlling your boost? PCM, boost controller, wastegate?

nothing stock boost everything the only think not stock on my car is the exhaust and a rice plate

**2K4SRT_4** · 12-12-2009, 08:24 PM

Well, if everything is stock. I would check all your clamps. A lot of the stock worm clamps like to come undone over time. Just go in and retighten them and see if that helps with anything.

definitly check for leaks.. Those times are terrible. Especially the 60 fts. the car that trapped 101 probably just needs the driver mod..

**2K4SRT_4** · 12-12-2009, 08:30 PM

a boost leak test is always a great idea.

yeah now would it be better to buy one or make one myself i was thinkin just buy one

**2K4SRT_4** · 12-12-2009, 08:38 PM

that would be up to you. if you can make one. then make one. if you don't want to make one and just spend the money on someone else's craftmenship. then go that route.

ok thanks bro

Definitely get t-bolt clamps perform a boostleak test and then ziptie all your vacuum lines as tight as you can. And last but not least either put high temperature copper seal.

Or just take the other route and just put back on the bypass plate and remove the mopar bov plate since the plate when not properly seals creates a leak under pressure. I would get an aftermarket bov like hks or leave it stock.
