Tunning question

[Gravy]

Something i gotta admit I'm not a pro at, last year i got my A/F ratio right and drove the car, didn't worry about power but just to be safe. Now I'm not looking to put down anything great, just get the car running as best it can, and today toying with the data logger, i came by something odd.

I took it out on the first drive of the year, didn't go faster than 60, and never went above 6188 rpm. However, on that pull in second gear i hit an injector IDC of 78.9. But with upgraded injectors, is the logger seeing the expected OEM 360cc injectors or the 450's i have in there now?

Also can't seem to find the info on what i'm looking for, i know under hard driving 11-12 is a good AFR, but what does everyone shoot for while cruising at say, 55 down the highway?

I have other questions, but i gotta google them before i post up in here.
