Is a coil on plug set up very beneficial to a mild build? I have an LSV 89x81.5 Pro 2's 206hp Kept getting a few different codes last season at the test and tune's. All stemming from the dizzy, basically replaced everything in the dist. and the TPS. If i did get it would I have to retune it or just set the timing back to what it is on the distributor set up.
