Dyno. Results & Tuning Information

I have setup this page to display the results of my dyno. runs and optimal tuning information for my car (in hopes that someone else can benefit from this, as well).

*The below settings are now inapplicable to my car, as you can see . . . the settings below indicate that my car is not getting enough fuel at the top on high boost. I resolved this issue by replacing my remaining stock fuel pump with a Walbro fuel pump, so now I am running two. I have not put the car on a dyno. since, because I am now tuning on a Wideband 02 monitoring system I have installed on the car. I will update settings as soon as possible.

My exhaust cam gear is set to -3, and when I had stock turbos and fuel . . . my S-AFC was leaned out -3% in the middle and -5% at the top per Andi Baritchi's recommendation. Now, my obligatory disclaimer: I have provided these settings in hopes that it will help someone in some way, and each car is different. My settings may not be optimal in your car, so just use them as a guide. I can't gaurantee they will work in your car. Also, thanks to Tony O. for helping me get some of my more recent dyno. data from the shop and help get it into my hands!
