I've been saying for two weeks that I'm gonna put this debate to rest once and for all. After work today, the 305's are going in. I'm gonna drive by my dyno shop on the way home and make an appointment for next week... gotta see when they're working.

Tonight after the inj's go in, I'll tune a little on the stock MAF to get it to idle fine and go for a drive... then swap in the RX7, tune a little and go for a drive. Once they're both swappable... I'll be ready to tune.

I'm also going to engineer my helper spring this weekend to see if I can quell some of the boost overshoot I've got.

I should roll over 450 miles on my clutch this weekend which will put it past the break-in distance, and it'll be ready for The Show. I'll be sure and film everything and will take photos and what not. Anybody in the area who know's Abacus Racing just off of NorthHampton Blvd is free to come by and watch. If they're open, I think Wed is looking good. I'll try to sched as late in the day as possible in case others are working (maybe take off early).

I'm going to tune for as much as I can get and be safe. If I can't get the overshoot solved, I'm gonna try for an initial spike to 12, and settle at 10psi... looking for 200 rwhp. We'll see if the RX7 is really worth anything.

I'm going to see what both do at 12psi as well once i get on the dyno...might try for the 28th. I just called to schedule....but waiting for a callback.
