    Yes adjust your injector slope, as known as LongTermFuelTrims (LTFT's) Go to Diablos website in there product section and put in your Preditors part #. It will show all the adjustments that be made. In red lettering you will see how to adjust, click that on and scroll down to injector slope. Follow those instructions EXACTLY to get your LTFT's and to adjust them. Any other ???'s let me know. I found that were Diablo set the other adjustments seem to be good.
