According to this chart a 9.06 eighth mile ET converts to a 14.13 quarter. Your 7.9 eighth equates to a 12.32 quarter which is exactly what you would expect. Well done.

i’ll take the guy who knows what he’s doing over the guy with more horsepower. Good stuff.

that said, we do need a comprehensive JB4 thread...

The fuel suggestions per map are for a reason. The B58/B48 platform is a little different than the Stinger platform but the fuel recommendations are more for "safety" in that the higher octane levels play a major role in how the engine timing is adjusted. Last thing you want is "knock".

This link is about as comprehensive as it gets for the JB4. There is a section specific to B58/B48 platform. Enjoy.

Wow...this is pretty cool..all stock on 93 is what I want. When you say non-ethanol gas...do you mean totally ethanol free gas or the standard pump gas that usually has a 10% mixture or so?

Map 4, and just 93 pure non-ethanol gas. No other mods on car.
