Who's going to tune it?

If it were mine, I'd ask the tuner for his preference

42 would be best. I have had svo 30's on mine for years and finally getting down to the intracies of tuning and found out my 30's were maxed out at WOT and causing a lean condition. The car is hardly driven and especially at WOT so really hasn't been that big a deal, but I figured I throw some 42's at it to get it the proper fuel at WOT.

Agree with all of the above. no less than 36lbs. 42 would be a safer move.
