i'm very tempted to bump the compression up on my gsr from 10.0 -> 11.3 via some pr3 pistons while it's apart. but i can't afford any sort of tuning or hondata etc at this point. my question is: will the stock ecu have any idea what the hell to do with the higher compresion? are there any cheap ways to get it working properly? maybe a chip or something of the sort? i know almost nothing about ecus and tuning, so thanks for any input.
