    i have a set of the 40k volt cops on my truck and just cant seem to get the tune done, anything over 1/2 throttle truck breaks up, so i ordered oem replacement cops from them today. new cops from the dealer would cost me around 600ish, new from them are 200 and have a lifetime warranty. i got the truck with them on there and its been a problem with the tuning since. right now rwtd is tuning and he told me to dump the granatelli 40k and get stockers, and i talked to jdm who always does my tuning also told me the same thing, sorry for the ramble.



    cliff notes: are granatelli oem cops any good?

    Nothing beats OEM Motorcraft COPS, the GMS are notoriously crappy, a few people have no issues, but the majority all have problems, similar can be said of any aftermarket cops.
