Yeah wasn't too bad, I am running 12J rears with 295s at present which help, tried anti lag but just span up like mad :-/ was set way too high. Once the pressures where down to 15psi it didn't even spin up going into second gear at high boost, was quit impressed just a shame about the clutch slip13.2 is good for them pressures dude should be defo in 12s il keep an eye out for u pal : )
