well, thanks for the tip Wicked. I was just thinking... 1600F is the limit before the piston melts. So isn't it a good idea to keep the EGT as far away as possible from 1600F is good? If I use that AFR, my EGT even at regular driving and cruising will be around 1500F. do you think it's fine? Because I just worry that is too hot even under normal cruising (driving) And since that 1600F is normal for a 2gnt. but since now we have a lower compression engine in there with turbo, don't we have to look at it as a different application? like.. no longer 2GNT? What you think?

That would be a no. It is still the same application with the same limits. The lower comp only changes the way we operate within those limits. Ex. Running the lower compression may make your EGT's a little higher than normal, but the limit is still 1600. You don't want to keep the EGT's as far away from 1600 as possible. If you do that then you will be running pig rich all the time to try to cut down your EGT's. EGT's are one of many tools to tune with, and with the addtion of MS they are basicly an oh shit guage now. Just get the fuel properly tuned and get a good timing curve and the EGT's should take care of themselves.
