Default Tunercat Help... need a baseline for XFI 280 cam in a 94 LT1

Got basically a stock shortblock, mildly ported intake runners, bowl work on intake and exhaust side of stock heads.

42pph injectors.

94 LT1

Need a baseline tune for tunercat so I can get started on tuning without continuing to dump so much fuel I'm washing down the rings at idle!

Do you have tunercat? Just go in and change the injector setting. You dont need a base line for that. BTW why 42 LBS injectors? Planning on going FI?

42s cost far less than 30s or 36s. I also want to be far on the safe side; this cam is the 280XFI from Comp, and is 230/236 @.050, and .570/.576 lift, so it should make very nice power if I'm willing to spin it high enough.

Injector size HAS been changed, but still way too rich at idle.

And yeah, I might have to pull the rail and make sure one or more injectors are not hanging open.

Anybody got a baseline tune for a high lift 230/236 cam???? I just want it clean enough to put on the dyno for a real tune.
