My car hasnt been runnning right, so I hooked up a scan gauge to see what was going on and at wide open it barely made 8lbs, I'm not sure what is going wrong. Any help would be much appreciated!
 
when you say it hasnt been running right, what does it feel like? and how is it differant then a month ago when you got it, how many miles on car?
 
what kinda fuel you running?? if your not running 91+ - computer will pull timing and open the wategate to allow low boost to prevent knock
