Hi all,
I currently have the stock Stillen SC setup making 380WHP with a 4.08 diff. I am about to get TopgunZ A to A kit and the 2.8" SC pulley and have it all retuned. Is the 4.08 diff going to bit a bit low for this sort of power and therfore should I replace the 4.08 with a higher ratio or go all the way back to the stock ratio diff gearing?

Regards.
