I have not but I would stay away from anything Granatelli...
Your not going to beat the performance of the OEM coil packs. Do some research on the forums and you'll see. Don't waste your money on after market coil packs.

They are one time use. Pull them to remove a spark plug and the connection at the plug tears out of the coil. Ruined over 10 of them this way only the have them tell me they've never had that problem before and I was doing something wrong. I only know of one way to install and remove a coil.
Interesting. Was this on a coyote?
Besides CPR, anyone have actual experience with these on a coyote? Dyno results?
American Muscle made a thread once, said they gained 7 HP from changing coil packs. However, it was forum consensus that that little change could have been dyno error between runs.
Even if they did actually add 7 HP, it wouldn't be worth the money.

I had the EXACT same problem! They acted like they had no clue how it happened! I sent them pictures and everything! Now MSD has come out with their coils also. I've had the granatelli's for over a year now and have never dyno'd the car so can't say if it makes a difference or not.
Plenty of fast cars using stock coil packs, no need for aftermarket coil packs!
My thoughts on coils are if it isnt missing why would you even mess with them? If the stock coils have proven to support over 1200+ hp why would anyone even consider spending money on replacing them? I look at it as a free performance gift from Ford that i dont have to upgrade.
They have a lifetime warranty don't they?

Yeah they had a lifetime warranty. But the Tommy Boy quote applies here. "All you bought was a guaranteed piece of ...... But every time without fail they would strip apart when I would check plugs. The last time I removed them 7 of 8 coils self destructed.
It's so irritating dealing with companies like that. Simply admit there's a problem. It's not the end of the world. Treating people like they're idiots and blaming them for their products short comings is not how you do business.

Just went an 8.0 @ 170 on stock coil packs.
They seem to work fine.

I hear ya, I used a ton of dielectric grease and hope they will just slide off next time.....have a feeling they wont but im sure that's my fault right??
I'd like to do a test to see if anything is there to be gained. I suspect the only way for it produce more power is if they allowed you to open the spark plug gap a bit.

Yep. Then they'll put you on hold and come back and tell you they just slipped one they had there, on and off 50 times and didn't have the problem.
