What's your ambient compression ratio? I looked but didn't see it posted.

Changed out the 95lb/hr and installed 71lb/hr injectors. Sending last written tune to Dave from B&G Performance for adjustments. The 71lb/hr injectors atomize much better with a cone spray. Should be much easier to tune for better street driving performance as well.


This is the Accel 95lb/hr spray pattern.

Dave wasn't able to do a complete boost tune. We tried a few differnt things that didn't make any difference. Part throttle and part throttle boost tuning is on the lean side. For normal easy street driving it's fine. It actually gets 15mpg around town even with a 3000rpm stall converter. Wide open throttle at 8psi boost afr is 11.2 to 11.4. Adding a pound of boost should get it in the 11.8 range. Had to add 45lbs to the back of the truck because it was getting out of control at wot. Unfortunately, the tune has to be reset after driving it around town a few times.
