Great compilation. Will the link be put on the top banner alongside 100+ tips?

In case I missed it, you may also want to mention that some mods may violate vehicle codes (and put in the requisite "check your local laws first!!!" warning). Ex: front wiper delete

That is AWESOME!! Nice job, I'm sure that took a bit of time. Another tip if you wanted to keep your wipers get a set of the new Bosch ICON style wipers --> Bosch ICON Wiper Blade - OE Bracketless Technology for the Aftermarket pricy at $20 for one blade, but they work great and hopefully help out slightly in the fight against drag!

*they are also called in general bracketless or beam blades

Yup, that's the plan.

Also, there is a mention about legality & safety in the blurb at the top.

Typo fixed!

How about losing your OWN weight! A lot of us could stand to lose 10-50+ pounds which definitely would improve our MPG. Seriously, that is an important factor in our search for optimal mileage.

I found a couple of mistakes.

1) Advancing ignition timing: If you increase power without increasing fuel flow, you will decrease the BSFC, not increase it. The goal is to minimize the BSFC, which is a measure of the amount of fuel used to do a certain amount of work.

2) Hot / warm air intake: I think that a higher air intake temperature will increase the heat transfer through the cylinder walls because of the increased temperature difference between the air and the cylinder during the power stroke. Also, hot intake air doesn't change ignition timing unless the engine starts to knock (or ping) and the engine is equipped with a knock sensor. If the engine is not equipped with a knock sensor then somebody may need to retard the timing to eliminate knocking. You may want to mention that power will probably go down with hot air intake because of reduced air density.
