Ok, last year I had set my best time and 60ft (12.74 @ 106.58 and 1.83 second 60 foot). Today I went to the track with my stage 4 stiegemeier port and 28" slicks. I ran .2 faster than my stock time. I was stuck in the 13.4x at 103.x. 6 runs, all with cool down of about 20 minutes between runs. Launching at 1800-1900rpm and WOT from the line, no tire spin, temps for mst runs 80-83 degrees with humitidy around 70%, 560 ish feet above sea level. Best 60 foot was a 1.99 on slicks (I ran my 1.83 on street treads with a 1200 rpms launch and rolled into the throttle). I have not run this slow since I have modded (unless I had a bad launch and spun like mad). Also, the truck is so slow out of the hole, but then about 4k rpms it just comes right into it and pulls like a freight train. I want to blame the port since its the only thng that has changed since last year. This is not a reclocked stage 4, its one of the originals.
And its not my tune, I am running 12.0+:1 a/f will 3500, then drops to 11.5-11.7 the rest of the way, no tq reduction, and 16* timing. Tuned by Sal.
so what should i do. I lost peak and low end torque with the port (dyno'd -17ftlbs peak) but gained hp and tq above 3800. Boost builds slow (im guessing this is the reason I have less tq). should i try a reclock or just say screw it and get another stock eaton? at this point i think a stock eaton with a #5 (instead of my #4) and meth injection seems like the way to go.
