I'm running march pullies, without the stock crankshaft pulley installed. I did install the march crank pulley. These were piggybacks but so far no problems after 6,000 miles or so. Will the steeda t/a or upr t/a work with this setup? thanks for any asssitance.
I don't see you having any problems since you are not using the pulley for the crank. If you are using the stock crank pulley the Steeda time adjuster would work fine.
I'd much rather use a timing adjuster than a chip. I have the SCT and dont like it very much. Shifts at 3200rpms at normal driving. Not the best for the money to me.
