curtis265 Im still running 7 psi, got a few tracksdays coming up in the next 2 months then Im gunna up the boost to 10 or 12psi., will definetly be hitting the 1/4 mile again, Keen to see 13s on street tyres. Not sure whether its the tyres / stiffish coilovers or whether Im crap at launching. I had 5 runs and wheel spin in 1st was ridiculous, couldnt get it to stop even I dropped revs on the launch ??
