Chris from CTA Motorsports has been more than helpful to me in the past. As Hector said, it can be expensive to dyno after each mod that you do--it adds up to $80 to the cost of the mod.
AFAIK, people have the CTA or the KKM. Several people have said the CTA is better than the KKM. I don't know of anyone that has the OBX.
I have had both. CTA is better, hands down.
