coils and coil packs??

Here is the dyno comparison of his results for any interested. Remember these results were repeated, not just a fluke. We made 3 passes each, the dyno sheet is representative of the average results compared.

That's a decent gain under the curve.

Hi,
Has anyone actually installed the Granatelli pro series coils and seen any gains? Was thinking of upgrading when I go Lund Flex fuel tune. Has anyone done the coils and tune and seen an advantage? Or has anyone’s tuner suggested doing the coils?

I would listen to Terry. He could sell you the product & make $ or be honest. He was honest about it. We all want that magically cheap horsepower gain with real world results and no negatives. There are pros/cons to changing anything on the car. If you truly want a set then get them.

Imho, motorcraft all the way. We have played with motorcraft, granitelli, and accell, and msd. Honestly motor craft was consistent and lasted much longer with fewer issues. All of the off brand stuff we saw failures within 6 months. Never had anything on a Dyno, but the aftermarket stuff is only good if you want to constantly chase misfires.
