Message I have about 1000 miles on my new motor and setup, and by early next week I will have about 2000 miles and will be ready to dyno tune my car. I'm not exactly sure where yet. I have been trying to get in touch with avalon all week, but paul hasn't called me back. I may go to rampage in queens but I'm not sure how maticulus they are, and I may go to a couple of local shops that specialize in american muscle cars but they are not very familiar with imports, turbos, or the AFC.

The first question I have for all of you is, do any of you have any tips to help me use my dyno time most effectively and productively.

second is what A/F ratio should I aim for on pump gas, and on race gas at WOT.

Third is What EGT reading should I aim for, and what is considered too hot (btw my probe is mounted in the manifolds).

forth question is for you people who have egts, I was wondering what temperatures do you read when you are cruising around moderately or with low boost. I feel like my car is running hot because the needle rises very quickly and doesn't stop, so I back off. I also haven't floored the car so I haven't really opened the injectors all the way.

I would appreciate any feed back you could give me.
