I can get a custom tune on a dyno with either diablo revolution chip or the new superchip. My question to you guys is would I see about the same amount of power gains from reputable mail order/e-mail tune from Amazon or RWTD as opposed to a custom chip? I really like the monitoring capabilities that the predator has i.e. you can log your driving and see whats going on. With a chip you cant. What would you do? I am asking the people that have had experience with both. Thanks
