Jay I had a qhuick squizz it doesnt say much about the r33s in fact half the site was down when i looked?? I had a tip secret tuned rom in mine it consisted of no daughter board but a reprogrammed EEPROM which is electrically eraseable unlike the roms with the windows (uv eraseable) which is what is normally used. So maybe your right
Im with you sydneykid, altho the wolf4d plug and play looks good too
If you use bigger squirters your engine will run rich across the board Al yeah..will need a whole retune
