I've always run 100 since I bought the car....it works well and is unleaded...which is nice for the o2.

However, if I started running the 108 or 110....which is leaded....could I see a drastic difference at the track? Probably a stupid question, but I'm trying to figure out if I want Joe to burn me a chip for that gas.

Here's my mods: stock block bored over .030 with forged pistons, balanced/blued, arp bolts/crank caps (2 ends), billet 208 (if I remember right...it might have been a 216), roller rockers, stock heads, 70mm tb, pte plenum, rjc plate, cotton fm, pt52, 3" maf/maf pipe with K&N and fresh air pickup from the valence, 50# inj, volt booster with syclone fp, oil relocating with upgraded oil pump, 3400 stall l/u, poston headers, atr crosspipe, atr 3" dp/crossflow 3" exhaust, dump pipe with electric cutout, poly engine/body mounts, fiberglass rear/front bumper...and the rearend is being rebuilt with Paul's roll bar and all 4 control arms, eaton posi, 30 spline mosers....feeding 255/50/16 bfg dots.
 
Yep - exactly. The higher octane fuel is basically just for knock supression so you are able to run more boost and/or timing.
