i start with 1 degree per pound

Could you use a JR BTC on a Turbo, or would you have to buy a BTM, the BTC is 100X better than the old BTM I had.

anyone know, you should be able to use the JR BTC on a turbo, but i would like to know before i get rid of it since i just got the thing, from jim the other day.

theres no reason you couldn't use the jr btc on a turbo.. i haven't seen anybody do it yet.. the btc doesn't depend on any of the jrsc parts to operate..

im running like 14 degrees of timing now all the way thru the power band,and this is with a maximum boost of 12 SC psi.

Are you enquiring how to tune your car with a BTM, how much to retard your distributor, or both?
