Sorry to sidetrack your thread again, just had a question I couldn't help but asking. How does that cam run (216,220) in terms of driveability with the Nelson tune? What are the idle characteristics, low end grunt and such? Reason being is because I'm getting a cam really similar to that, with 4 degrees less duration on the intake side and 2 less on the exhaust, and a hair less lift on a 4.8. If you could answer my question I'd greatly appreciate it! Thanks
