I had a 3" exhaust on my 14B with no dump at all and zero boost creep. You just have to properly port the wastegate hole, turbo outlet, and o2 housing.

My college roommate had a Big 16G with a 3" downpipe, test pipe, and 3.5" exhaust with no boost creep problems either.


Also Autometer makes a fine boost gauge for $45. Fuck the Greddy gauges unless you REALLY need peak/hold and you have a lot of money burning a hole in your pocket.


And I really would recommend the Walbro 255 pump over the 190. Changing fuel pumps is one of the most annoying and time consuming things you can do on a DSM. Especially the older DSMs. Get the right pump the first time. It is $105 shipped from www.autoperformanceengineering.com. Do not get the high pressure one and you won't even need to get an aftermarket FPR. I swear people think the Walbro 255 needs an aftermarket FPR because they are morons and get the high pressure pump. I get 400 miles to the tank in my Talon in 12's trim on pump gas with the stock FPR and Walbro 255.
