    Do I need a fuel controller?

    1300 non pv engine with a milled head. It has 130, 125, 120 psi, one dome has some damage. It had 115 in all cylinders with stock head. Question is: do I need a controller? I bought one from a member of the forum and is broken (yellow led stays on all the time). Thanks

    Take it off, its bad if the yellow light stays on. You have a milled head with 125 psi then your guage is way off or its a stock head.

    I had 115 with stock head. I might have to put new rings on those pistons.

    are you doing the compression test correctly? you should be seeing 145-2

    milled head> yes controller needed as is premium fuel

    My gauge was good but I didn't do the test right, I have 140 in the rear cylinder and 150 in middle and front. I had some corrosion in the controller plug on 3 wire connectors and I clean it, no result, same thing yellow is on all the time.
