I have a smal problem with my focus st170
last weekend i changed the exhaust camgear for an CFM adjustible one and set it on 6 degrees retard like advices by CFM

Other mod are:
Bluefin chipped (tune 4)
K&N57i inductionkit
67mm CFM throttlebody
2,5 inch SS custom decat and 2,5 inch SS catback system

The camgear was the last upgrade and before that the engine was running very nice and smooth with all the other mods.
But after i've done the adjustible camgear, when in low revs (2000-3000 rpm) it misfires when i go full throttle.

I have no idea what is cousing this problem.
The only thing i can come up with is that maybe the bluefin is not build for this upgrade.
can anyone please advice me on what to do?

I have allready send an email to CFM and also to Bluefin but no response yet.
