Would it be good to buy one to self tune my 87 with a 350, full exhaust, no cat, 3.73s, and some intake parts. Currently running a hypertech chip, and am running rich. I have an Rpm surge almost at all times and motor ping. Even stalled a bunch of times. Motor is new from S&S and was converted. Thoughts?

Re: LM1

do you have all the chipburning equipment, the wideband isn't much use without being able to change the tune.
