I'm not sure why they're so high either. I used DIYs base map, untouched DIY Spark map, stock 1.8 injectors, required fuel 11.3 per the megatune calculator, rebuilt head, stock intake manifold, stock exhaust manifold, monsterflow intake, no AFM, stock intermediate pipe, empty FM high flow cat, 3" Enthuza TurboRacer catback. I haven't dynoed yet, but it seems to be a noticeable difference in power between a stock 1.8 and my car. In a race between my friends supercharged 1.8 and mine I was like 3 car lengths behind him at the top of third gear and his car runs low 14s with **** launches.
I didn't remove the boost cells in hopes that soon I'll have my turbo installed, but thats still a ways out unfortunately. That stupid A/C Drier is in the way and my solution to move it has failed due to difference in fittings and connection styles of the drier. I'm about to evac the system, remove the drier and cap the lines then worry about moving/hooking it back up come spring time.
For Idle I can't seem to get a solid ~900rpm smooth idle at anything less than 12.5 - 13:1, if I lean it out to 14 or 15 it 'bumps' and misfires a lot. Also as of late I haven't seen it really IDLE at anything below 1100rpm or so.

This may be a bit stupid question but , my car is completely stock and with my LC1 hooked up i cruise at 15.5 and can easily average 30 mpg.
Should sam not be getting the same as me as you are not in boost when you cruise? or is it all the in boost situations which bring the average right down?
