Sorry for the question but I’ve been going round in circles for weeks and was hoping that i may get the answer here ?, before i get shot down in flames I’m not 17 and trying to make my 1.0 Corsa faster Lol, does anybody know if the rev limiter can be raised buy 2-3 hundred revs on a BOSCH M1.5.5 0261206169 because my 15 old son races in a 1.0 class and we are hitting the limiter 3/4 down the straight so just need a tiny bit more, thanks for any help that can be offered
