Are you running a stall converter
Are you running a stall converter
2005 rcsb silverado 4.8L, Full bolt ons, obx lt's, ory, comp xr265hr hi lift, Nitrous outlet plate kit, built 4l65e, J-H shift kit, 2500 stall,3.73 G80 , 3 inch spintech cat back, tuned by Rick at Synergy motorsports
What is your tire size on the 22's? I was thinkin maybe if you got a smaller wheel and tire combo in the back, that would help allot. I would think you would be ok on the tune unless it was running too lean because of the increase in air flow... But I think the pcm self adjusts for that. Like he said above a 3000-3500 stall will help ALLOT!!!
