So I have the Sealey ferret adaptor TL95. Works great on my 1989 F350 non turbo. Got a new truck some months back and it has always ran a bit ruff. 1989 F350 with the banks turbo kit on it. Hooked up today and for the life of me I can't get the RPM to go under 9900 RPM on my timing light. In fact it just stays there no matter the RPM. Tested on my other truck works perfect. Tried it on different injectors on that truck but all read the same 9900 RPM. Sanded the injector line good also. Tried it back on the other truck and it works perfect. Im thinking there must be some sort of interference I'm picking up with this truck. Anybody have any thoughts?
