So what dose the standard s400 come with? I remember Pat using one and ran something like low 11's said it was a good charger for the price but he went back to the gt4202r for the 10's
With the right trans tuning, all the suggestions above will go 11's and still be suitable for a daily driver.
PM Mike L and ask how Casper runs on the street with a GT42Mag.
Yes, I can go a couple tenths quicker with the GT4202 than the S400 (3.0"), but the S400 has a wider operating RPM.
