One owner 12k 87 GN. Ordered this car late June 87, got it sept 87 paid 18k.Jan 88 transfer oversea's spent many years there. Hence the low miles. Dec 2012 had to take the factory tires off and replace. Car then was no longer a virgin. Here I am 9 months later and 20k poorer.I have a scan master and power logger.Thinking from what I read on this site I need to go with a wide band. What do I need to buy? I am unable to find anyone in the Charlotte NC that knows how to tune these car's You would think with NASCAR all over the place there would some old guy that would know these cars.So I guess this old man will have to learn myself. Please help.
