If you text Scottie he has a nice base map with all this on it that I use all the time 40 shipped for a chip for a p28 ecru if I'm correct . Did that answer your question ?
I think the 6300 red line is wrong that's got to be a non vtec . If not it's just because they come behind a auto tranny not a five speed . These motor are really well built and will stay together no need to go over 8,000 though when your losing power.
