I think I'm ready to get my car tuned I was going to bring it to coupe performance I have to get an adjustable fpr before I do but I don't think he can turn my egr off do I need to have a programmer to do that or will a different tuner be able to do it he said about all he can do is dyno it with an a/f meter and adjust my fuel air mixture and of coarse re time it any info would be greatly appreciated
