Hey guys i gust bought a 88 gtu the other day. I had a really fast first gen with 230 hp and now this car feels weird not being fast. I am new to the fuel injection and I was wondering what are all of the upgrades that I can do to get more power without going turbo quite yet. The car is all stock right now. thanks

I'd start with intake and exhaust. You can start by going here...

https://www.nopistons.com/forums/pub...#>/BURNOUT.gif I got a question, if he replaces tha exhaust and intake , what is best tha single or dual exhaust. Personally i am going wit tha Racing Beat header and presilencer and a 2.5 all tha way back to a single r active racing medallion muffler. does that sound good and do u think i should get some good horses going single? https://www.nopistons.com/forums/pub...1047683785.gif

I have the dual exhaust set up, and I love it. A BIG power gain! It is a bit loud though. I had to take my emissions test the other week, so I'm sportin' the stock exhaust right now. I hate it! :madgo: It takes SO DAMN long to rev up. I feel pitty for anyone still running the stock exhaust. Here is a link to the exhaust I have...
