hi, im off to usc this weekend and will be having a few racing against some of my mates rs turbos, the thing is ive never done one before, and my mate has done a few, our engine specs are similar.

Is it best to redline my car, or change at where my peak power is met, mine is only around 4.5k as my head is standard making my car with a nasty boost spike and very punchy

my mate done it in 14.41 the other week, i reckon i could beat that, but i think i could do with some advice first!
