ok here my story, iv got a s2 r33 with a fmic, full straight through exhaust, pod and bleed valve set to 10 psi, everything else stock, suspension ecu etc
i had the stockies on with hardly any tread on the back (225's) and i have never been able to chirp 2nd, obviously i could spin the tyres around a corner and drop the clutch for burnouts but yeh, if the car was rolling in first and i floored it, it would do nothing, i think the problem was the were inflated with a low psi cos yesterday i got 18 with 235's and now it chirps 2nd really easy and spins for a while after wards lol, the tyres are nankangs if that makes a difference
now technically shouldnt the 235's with new tread be harder to chirp or sumthin lol, im puzzled, i think it might be doing it cos they are inflated alot more the my stockies lol i dunno, thats the only explanation i can think of hehe
