1badeagle Posted July 27, 2009 Share Posted July 27, 2009 I've recently ran into a power issue. I plugged my pop off valve and added a nxs manual boost controller set at 8 psi and cut my converter off to replace it with a straight pipe. All was well and it ran really strong. It would chirp the tires going into 2nd gear. Now, I cranked the boost up to 10 psi and it seems very slow. It wont chirp the tires anymore. Also when I started it the other day I was leaving walmarts parking lot, I pulled onto the road after starting it and floored it. The boost gauge went up but it stumbled on itself really bad and didnt go anywhere and ended up backfireing. It feels like its losing it top end power. Could it be leaning out now? Thanks for any ideas. Dustin Quote Link to comment Share on other sites More sharing options...
woldson Posted July 27, 2009 Share Posted July 27, 2009 Maeby, turn the boost back down and see what happens. Quote Link to comment Share on other sites More sharing options...
280zx 2by2 Posted July 27, 2009 Share Posted July 27, 2009 im not a turbo expert at all but isnt that compressor surge? he might have turned to boost up too far for the stock turbo? Quote Link to comment Share on other sites More sharing options...
1badeagle Posted July 27, 2009 Author Share Posted July 27, 2009 ok i guess ill try it down lower Quote Link to comment Share on other sites More sharing options...
1badeagle Posted July 30, 2009 Author Share Posted July 30, 2009 Ok, I turned the boost down to 8 for about 10 and it feels exactly the same. But it may just feel slow since i was driving my dads 04 mustang. Its much faster than my car:( Quote Link to comment Share on other sites More sharing options...
