I have a 87LX that is mostly used for weekends (racing) and some driving , this is a full weight car , looks like the day I bought it! It has a 347 with c-4 X pipe and dynomax muffs 3.73s It runs O.K but when you start it it idles like a blower car until warm it also passes Maryland fast pass emissions. Would a custom chip help ! or a intersepter? (old) Ron Anderson I think has something like it also, Must be easy to use! 11.84 @ 113.7 1.58 60ft Thanks
