Small Turbo, 255/60, 10% slip on the converter - would have to tighten up the combination to get more MPH. Yes, trap speed is probably a little low. A good NLU converter <5% slip would add some MPH, a 275/60 would also.Seems soft on the big end
The slip was for comparison to what is in my signature, and to add to the who is using Bison's alky plate.
Before TE-44, stock dutt neck intercooler, alky in the up pipe. 11.53@114.1
After PT5858, PTE SLIC, Bison's alky plate. 11.24@117.8
