Contrary to what people say, you can have a clean burning engine that makes great power.

As for running premium...why? Do you have detonation issues on lower octane? Ideally you want to run the lowest octane possible. Higher octane does not add power, and can actually hurt power due to the slower burn.

Hatzie was on the money with the open element filter - you will lose more power than you would ever gain.

Personally I would avoid TBIChips and go with http://www.dynamicefi.com/ and tune it yourself.

I run premium in all my vehicles. I never like ethenol and it for some reason seems to gum up carbs and tbi units. I have done it my entire life. Just seem to have good luck with it I guess. I understand the open filter but I’m not really looking for power quite yet. Eventually the new engine will be built and we will go from there. The egr I’m on the fence with, I’ve heard many different ideas with t and I appreciate them all.
