I recently installed stage 2 heads/cams on my HD. Went to get it tuned/dynod and only got 377/404. Along with the heads/cams Im running 60#injectors,1600SCT MAF, Manley Rods, Probe Pistons, High vol oil pump, Single blade, 2.73 upper,10# lower, EGR delete,NGK TR6. At 3800-4000 the truck would stall out causing a failed dyno run. Checked MAF, it was clean so i rescheduled and decided to change fuel pumps so i replaced them with 255's. Is it me or should I expect more from my motor? Im scheduled to go back in next week hopefully to get better numbers. Any ideas on what i should expect? I will also add that it was 102 in the shop (according to my truck) and my Intercooler pump was acting up also causing more heat.
