friends eclipse slow

[b18c1vic]

I'll give the basic rundown of my friends eclipse. He has a 99 eclipse gst. It was pretty fast when it was stock. We started modding it put on a greddy type s bov, 20g turbo, fmic, apexi 3" turbo back, and some other little stuff. so to the story, the car was running ok, we put on the exhaust without the muffler attached, with the 20g turbo, intercooler and bov already there, and the car ripped, felt like a mid to low 13 sec car. We put the muffler and it slowed it down to maybe a 14 sec car. then a couple weeks went by and the car just kept getting slower and slower, til now its at about the same as stock. We took it to mitsubishi and they said nothing was wrong with the car and it ran perfect. It may run perfect but its not fast, also the the boost spikes at 20 and holds 18 psi with no fuel cut. Does anyone have any idea what the problem could be????

I finally had a chance to test the IC pipes today. Found two leaks; one IC pipe that has a severe leak and needs to be replaced, and the second was the gasket on the BOV flange.
