@Crisis What octane fuel are you running with your Racechip and what map?
I was running Map 5 on 91 octane for daily driving, but went to Map 7 on 94 octane with octane booster when I took it to SIR.
Originally, Racechip recommended nothing over Map 5 on 91 octane but have since clarified that if you change to narrower gapped plugs (which I did) you can run map 6 & 7 on 91 octane. So now I'm usually running Map 6 on 91 octane.
