Hi.Our early SC400 has been modified (to wit -computer reprogrammed using TRD [Torrance, CA] equipment along with my own coding, a true common chamber Secondary CAT w/ dual Dynaflows exhaust, the usual K&N air filter, and modified airbox). In any event, I want more - Electric-powered supercharger (it looked like the paxton unit), NOS, whatever... <br><br>Also, some observations on tires - Dunlop SP9000's 245/50/16 - quiet, smooth powerslides, easily controlled recovery from same, very good traction, etc. -I replaced my Goodyear GS-C (ie- mid90's Corvette OEM) tire - less traming, tracking pull in grooves, noise, wear, etal. Worth a look - also they are not expensive.<br><br>Dash lights - argh! The lumination of my gauge needles are problematic - sometimes 100% lit, and sometimes not (light ceases in the center area of the needle...)depending on the heat...<br><br>I will post a slew of maintenance items and such shortly. I have always haqd faster cars, but this Lexus is FINE.
