I'm having some trouble with my thrasher 93 chip ,the car starts surging and bucking at about 4800rpm with or without boost or alky when I change to a RA chip the problem goes away.This may or not be the fault of the chip but I have heard there are better chips out there for alky systems.Can anyone give me some advice as to who's chip I should be buying.My combo is as follows-GSCA,200-200 cam mild ported heads&intake,GSCA valve springs,PT-51,TH-DP,ATR 2.5 duels,stock IC,Blue tops.Razors alky kit.Any advice would be apprieciated.
