Actually there is a little bump between 6k and redline where it got a few tenths leaner and there is a corresponding bump at the same point in the HP&TQ plots where the power was up

You want to shoot for ~13.5 across the board (plus or minus a few points).

Definitely worth it. The HS ones will work just as well too.

Actually it's an auto, but I think that's what you meant to say.

if we have a 23% loss then doesnt that make that "255 hp" statement not so false?

howd they manage to get your car not to downshift?? Or did they go part throttle, then floor it once they got to 3600? The results are usually better when they get up to 4000, let off till 3400, engage the dyno, and floor it.

From what I saw, they went part throttle until they got around 3600 rpms. Next time I go, I'll ask exactly what they do.
