Default RE: What MPG and HP increasing devices NOT to buy!

ORIGINAL: Chopper

I installed a Steeda timing adjuster set at +3*.I adjusted it to more advance untill the CEL came on.then Backed off one degree.After testing the new part for about a month of driving the same road at the same speed and filling up at the same pump I came up with a gain of +2 MPG's.If you get one of these the timing marks are just for reference.It would be impossible to install the sensor exactly the same as it was inside the engine.It's not hard to adjust though.

Do you use 87 octane or higher now?
