Al, Question after custom tune ??
Al, Question after custom tune ??
Al, I had you do the custom tune on my 03 at the Charlotte location. You set it up for road racing and on the safe side. I just got back from an event this weekend at VIR and noticed that after making a turn and getting back on throttle I would have a lot of smoke from the exhaust. It looked more like fuel than oil. The people who were running with me said that I was blowing flames " Looked cool". Is this normal since I had you tune on the safe side? Also just to note that I was running 100 octane... Thanks

I wasnt quite sure how far to safely go with the boost level. I was jumping to 24 out of the turns then holding at 22. But I assume that either way the running on the rich side is a better safety margin.... As long as its causing no issues..
Take it as you wish.. but putting 100 octane in a car that was tuned for 93 is just going to make it even more rich. I was tuned for 22psi on pump 93.. I run 24/25psi peak with 100 octane in.
I wouldn't go too crazy if you don't have means of monitoring your AFR. I was talking like 1-2psi.

When you are doing road racing the coolant temps get very hot and the ecu adds in additional collant temp enrichment corection
The car will run a bit on the rich side
However - this is very safe and your car will last with no problems
For those who do not drive the car every day I have ways to map the car so the a/f stays more lean in a racing situation and will make more power - however this is not recoemnded for street cars that run pump gas
USING ONE MAP for street and race involves some compromise - here is is a few whp and being a bit on the rich side
