so you have tried two different distributors with no change?

 

Yes 2 different distributors 2 different AEM EMS my old 30-1040 and now my new 30-1050 and no change.

 

looking for any ideas

 

check your grounds. The ground on the water neck is the most important.

 

Its connected I took it off and cleaned it im going to give it a try. I have 3 extra grounds that I made from 8 gauge wire. Valve cover to core support, Trans to Frame, and Intake Mani to strut tower.But I have had those for a while and the car still hickups at arround 7600 with load.

 

thers a filter that can be placed on the oem crank trigger that helps redice the noise made by the dizzy or u can get the tony1 trigger thing

 

do a datalog and log all your inputs on fast channels, including vss.

Tomorrow is going to be 70+ degrees no rain so im going to test my car, I took the EBC off running wastegate I want to check if this could be the problem.

 

I removed the Greddy EBC and I went on the hyway and the problem seems to be gone, my tach goes to 9K no hickup and not loosing tach signal, I tried it 3 times and worked good. I hope that was the problem.
