Tuning without a dyno...can it be done?

[SpecM]

NO, but then again I have easy access to a dyno, but yes I still need to pay for it. and it is worth every penny. I can not imagine doing 3rd and 4th gear runs at WOT on the street trying to pay attention to a O2 guage. STUPID!

well duh, use a datalogger. Don't look at anything but the road on any WOT trip

or just have someone driving and someone tuning...

you can do just as much with 2nd and 3rd. 3rd gear WOT isn't so bad, it's not so far over the speed limit (~90mph) that I can do it on an on-ramp and not really have to worry about anything. I rarely use WOT in 4th gear on the street anyway, it's too fast (94-100something mph).

and of course, datalogging. duh. :p
