Not interesed in power, only carrying corner speed

Out of curiosity, how exactly did your tuner sacrifice peak power for response?

Lap times aren't everything and I really don't care, I was just trying to stress a point, and it seems you are determined to go off on a a different tangent.

If I knew how to tune, and understood it, I wouldn't have a tuner, i'd do it myself. But overall, he generally made it a safer tune. He overlapped VTAK change over which gave me a bunch of mid range response, and by playing with fueling it gave me freaking s**t loads of response, but lost a few KW of peak power.

Anyways, 5W-30 makes an engine (Well, a B18C7 anyways) respond much better then if using 10W-40, regardless of brand, price or protection ...End of story.
