Loss of power after 3" downpipe installation
Last weekend I replaced my stock downpipe with a 3" from Diamond Eye & cat delete pipe as well. I had the tranny out to replace the dual mass flywheel with a single mass, so I thought it would be a good time to do it. I have the DIY air filter on order but have not installed it yet. It used to loose traction on a gravel road in 3rd gear at about 2,000 RPM. Now it doesn't peak out until about 2700 RPM. When i first started it after the install I heard a lot more turbo whine, but that has gone away now, too. I am running the stock program. Does anyone have any ideas what may be wrong? Thanks, Scott
BTW it is a 1996 basically stock except for the exhaust & flywheel.
