Rev Limiter coming in early
I have a 1994 Z28 with 70,000 miles. I just changed the opti and all is running great. I couple of days ago I was in second gear and I was WOT going up to 6,000revs. As I was approaching 6rpms I felt a little a hesitation. My question is what is the rev limiter set at. And when I felt that hesitation it felt kinda like the old opti when it needed to be replaced, but not as bad. Anyone know, also I know the rev limiter was not being hit.
I was hitting about 5,800revs when I felt it.

Maybe
It could be the coil, however I dont think that is the culprit. You never said if the wires are new. What kind of wires are you running? I just noticed headers in your sig, my friend, check #4 and #6 wires. Mine likes to eat those just enough to arc over and cause a high rpm miss.

Stcok settings for an M6 are 5,886 rpm in 1st gear, and 5,805 rpm in 2nd thru 6th. But the rev limiter will feel like more than a little hesitation.... it shuts the fuel off with a "bang". Also, the stock tach can be screwy at the top end... mine was going to 6K with the stock rev limiter, but a scanner showed the true rpm wasn't over the 5,805 rpm limit.

I changed the opti last week and changed the plugs and wires a month ago. Acdelco platinum plugs with 8.5 MSD wires. I do not have the lumes on the wires(wire seperators). But I think the wires are insulated enough that they would not arc.
