I don't tune around 20 psi...or even 23 psi. At 20 psi with the 02's at the traps showing 820-830, I come back in and turn the rod in 2-3 turns. The extra boost brings the 02's down to the 770-780 range...and the car pulls like a freight train at 23 with the 6262. My thinking is this. Why bother leaning it out at low boost...and take a chance at smoking a pair of head gaskets. Why not turn the boost up a couple notches...leav e it fat...and haul ass. That LU convertor is prolly less efficient than my NL convertor until yours locks. Top end charge is where you're gonna fly.
