Quick question for you AL, I just got my ecu back from you here in NM, you tuned it for 99. octane and Buschur stage 4 x-cluding intercooler....I have been running it and all feels real good, but today it is 85 degrees outside and I put 109 straight octane....17 miles later I through a cel for p0171 too lean... I wasn't sure is it the weather or it the gas at 109.. I did not know reflashes still through cel's? please help
