Hello,

Decided to go with a NSP (No spring required) BTR Truck Norris cam in my 2005 5.3L. Will be installing it this month just wanted to get some opinions from people who have run the truck norris cam? Any issues with the stock converter? Truck is completely stock except for the corsa exhaust and a corvette shift servo.

Also, what is tuning like? Do I just find a fella who does HP tuning or something similar or do I really have to go have it dyno tuned over just a cam swap?

Thanks
