logged and set ltft's all good ,what else can i adjust, timming? and will it effect the ltft's?also what about WOT?

[RedJewel2SS]

the tunes are already optimized for timing, however when you do a WOT log if the TKSR is near or above 1 degree, then you'll have to retard the timing by that much to solve that problem. if your WOT log shows no timing adjustment needed, then just adjust your PE Enrichment per the recommendations in DSLogRedux

also, the diablotune is more or less keyed on 91 octane fuel. going more aggressive in timing goes hand-in-hand with having high enough octane fuel so you don't clatter. Do you have 93 available in your area?

In the end your timing potential/entitlement will be limited by fuel octane rating/quality.
