I Dyno-tested my truck today. I replaced the stock exhaust with dual Borla Pro XS mufflers (cat back) and a drop-in TRD hi-flow filter. The dyno showed a consistant 308-310 hp at rear wheels in 3rd gear. 285 hp in a fourth gear run. Lower because the rev limiter is set at 100 mph. Torque was consistant at 318. The thing that was very noticable, the air/fuel mixture was very rich. Like< 10. After we took the the neg cable off the battery and let the cpu reset, we got the highest hp at 310 and the air/fuel ratio at 10.1. When someone comes out with a tuner I can actually produce near 325 by changing the air/fuel mix to make it a little leaner to 13. that's potentially another 25 horses. HELP!!!!!!!!!!
