Iv'e got a 3-3/4" tach on the steering column with a mini programmable shift light, and my Rev N nator box is set at 6,500 IIRC. I still need to get some subframe connectors welded in, and some better rear tires, before I will take mine out for some testing in the spring. Once again, great job on the Duster, keep us posted on any new mods, or track testing
