bodge, yeah i got the red tops for a steal, so i kept the begi, just to add a bit more fuel, but we'll have a play tommorrow. i cant see any problems keeping it in the rollers, more how much fuel im gonna get through looking forward to tommorow.. dont worry brett, laptops in the car as we speak. it was 330 before on just the begi, so lets see, but the c2 chip has knocked 0.7 sec of my quarter mile, and that without any fine tuning. so if that s any indication, then roll on good times
