the ecu will pull a little timing, never understood why apr had 91 and 93 and no just a "chip" that adapts to octane, like giac, but don't buy giac its a few steps back in terms of refinement. Apr runs as smotthe as stock with more power.

APR uses the 91 and 93 octane versions so they dont have to run excessive timing correction for 91 octane enabling the ecu to pull less timing due to knock and as a result run more BTDC. cheers! Mike
