[Supras] Crazy Lex tuning thought

[jhutto at ptb.boehringer-ingelheim.com]

Yea I got one on my 550/ Lex/AFPR combo gotta take a lot of fuel out under
boost and is still somewhat rich but safe (so far). I want to creep up on it
some more but doing it while taking quick looks at the WB is not the best
way, I need to get some trending hooked up or take a trip to the dyno.

I think most find the installation of a S-AFC II more practical.
