trying to learn how to tune my car,i currently have a decent tune from someone else...afrs at idle are about 14.6-15.4 in between those numbers,usually not higher then 15.3 when idling...at wot its about 12.5 and partial throttle 13.5......car runs pretty smooth,but i noticed if i drop until neutural,idle sometimes drops down to 500 rpms back comes back to normal...i have a laptop,

2006 scion tc

dezod s1 turbo kit with 550 dw injectors,garret 57 trim turbo...

is there any guides or diy here on the forums to guide me on what changes to make,i know,go to a pro and have it done,but i figured i would ask,see if someone can help or guide me to what changes to make

 

at wide open you want to be below 11.2. i like 10.9. at idle at 14.5 to 14.8. at little throttle. 12.5 to 13.1. but best is to be done on a dyno.

 

WOT -11.5 , cruise 14.5-15ish.
