Timing tuner issues???

OK....so I have an 02 z28 with 103000 miles. JUST CHANGED THE PLUGS....so every once in a while I will run it and at 5000rpms it will sound like Im hitting the rev limiter....when clearly my limiter is set at 6600. I have a timing tuner which connects to the crank position sensor and I am thinking that maybe this is the problem. So I go out from 50 in second and punch it and boom rev limiter at 5000rpms. Go right back out again and its perfect climbs all the way up to 6600...What the hell is going on?????

Do you have the by pass plug for the timing tuner that allows you to disconnect the timing tuner without unplugging the timing tuner harness? If so, plug that in and see if it still does what its doing , if so then disconnect the harness and see what happens you may have a malfunctioning unit, i've heard a couple guys are having issues with these units my tuner doesnt too much care for them so on his recommendation I may be switching to the MSD timing twister or the Harris speed works micro edge unit!

i had a ton of issues with my timing tuner, went back to a msd window switch and voila, the n20 works like it should again.

Like stated above i'd unplug it and see if you are still having the problem. If not then the box might be going out on you.

Have you contacted Full Throttle and asked them if they have had this happen to a vehicle before?

Yes they do offer a better unit for pulling timing
