[s-cars] Re: wrt pushing RS2 to the edge...

[Sandy Sligh]

Well, you can't really run 28lbs without racegas
because won't the motronic dial back the boost if the
knock sensors start talking? I mean, you might see it
for a quick burst before its starts to dial back..
right? (I wish I had paid more attention to what the
boost gauge was doing down at VIR, btw)

Isn't that basically the reason why you can't easily
run a WGFV controller, like an HKS product, because
it'll hold max boost, ignoring the complaints of the
ECU to back off.

I get the feeling that Bruce dreads checking the list
mail for fear of seeing a post from me that reads,
"Engine knocking? Low Oil pressure? Is this bad?" ;)
Just kidding. I trust the S4 with my life. Hey, if it
could withstand your ferocious driving ability, it can
certainly handle my fumbling attempts.
