Just installed my new APR chip today.
I have just noticed that between 2 and 3 gear
there is high pitched sound, i cannot really
explain it. in any case, can somebody tell
me what pinging is. i'm not sure if i'm experienceing this or is it just my turbo kicking in. Thank You. Also, is gas different from differnet stations, for example a MOBIL and a
MERIT here in Massachusetts.

Pinging Is premature detination of gas vapors. (not normal)
