Hi all,

I've got a new crate engine in my 2011 Coyote. It's got the 2015 cams/Phasers/chains etc.

I've been told I need to change back to 11-14 VCT for the engine to run properly. I keep getting bank 1 and 2 intake cams over retarded codes.

I've heard that the S550 exhaust cams can be used with the 11-14 so I don't need to change them, is this correct? Or do I also need to change the exhaust cams for 11-14 ones?

Anyone know? I have a feeling I can leave exhaust cams in there but need to change everything else back to 11-14 inc exhaust Phasers?
