Scott,
That car is amazing fast, 4.78sec. Is that also a 3.8L set up? I know a lot of guys do not like to talk to about their set ups here unless they know one another. My apologies if I am being rude.

we've found that if you use leaded ALL the time and drive frequently the effects on the non leaded valve are minimal and really doesn't do much. now if you drive occasionally and use leaded fuel with the non leaded valve that is where you are going to run into issues.

all of that is now irrelevant info now because all 38's come with the leaded safe valve
