i finally got a resinator put on my car, so i;ve been driving it around more. I still have no fuel controller for the 820cc secondaries and walbro pump. but dispite what i have read and what other people have warned me about upgraded injectors w/o a fuel controller, my car seems to run fine at 7 or 11lbs of boost, all the way up to redline with no bogg or stumble.? why??

thanks,,

Ya I have 720cc secondaries and a walbro and my car only stumbled when I removed some fuel from the upper RPMs with my s-afc. I guess that its not that incredible amount of fuel to make it stumble.

whats the difference between a detenation and a Bog or stumble at high rpms, differnce in sound that is, I have my s-afc turned up pretty high and 7k, and in 3rd gear after a down shift from 4th I get a bluurrrb sound and my car runs fine afterward, I also have an FD fuel pump and I may be leaning out but in 4th I took it to 6500 at 9psi all the way......i also have a resenator

What does the voltage off your O2 sensor read??? When I had my talon (20g, fmic..etc etc) I'd try to get it to about .90v. Mind you that this tuning was done on a narrow band o2..but hey it got the car to run an 11.98 so it must be an ok method. If you can take it to a dyno or spend about 300 bux and buy or build a wideband o2. If you are NA then you probably want to tune for about .80v or so. The website for the wideband is: http://www.techedge.com.au/vehicle/wbo2/default.htm

I was watching it and it read rich at 6500, but I was paying attention to the road after that, so I just hook up a voltmeter to the O2 sensor?
