vapor dash question

[badinfluencerace]

just wondering if anyone can help me with the tach problem i have, it works good up to around 3/4 throttle which is about 6500 but when i go full throttle it goes back to around 3000 rpm kinda strange , its hooked up to the primary coil wire and programed correct and has a good ground so kinda lost

Primary wire as in the signal wire from the ecu to the coil? Or are you talking about the coil high tension lead? Most of the time when they are wrapped around the high tension lead they are inaccurate, in my experience. Try connecting it directly to the coil signal wire.

Any chance you have a 7800 RPM limit cdi?
