Have a LT-8. The injectors were leaky so I changed them. I have 550's below and 1000's up top. I changed the throttle body and tps and now my car does not boost up and craps out at about 3600 rpm. I calibrated the tps and the timing is okay also. It revs a little sluggish and will just stop revving and backfire at 3600 rpm. Can anyone tell me why it is so overly rich and why it is doing this.

 

What's your RPMstg and MAPstg? Are you still in normal mode? If so, shoot us your load fuel map values, please.

just out of curosity, did you change the injector duty when you changed the injectors from 550's to 1000's? leaveing the same map in there for those injectors will basically double the fuel output when they come on due to the duty cycle....

I had 900 secondaries before and I just changed them to 1000's. I will get the RPMstg and MapStg values. Yes I'm in normal mode.

 

hrmmm, where did you get injectors from and how much did they cost? if you want to get rid of your old 900's ill gladly take them off your hands.... shoot me an email at bejbis@comcast.net, or an IM on AIM at screen name Bejbis
