Just so you know, that Tornado is probably costing you horsepower.
At the very least, it is NOT gaining you anything.
Tornado, Electric SuperCharger, Oil Additives, Hotchip/Jetchip/stupid ebay chips, etc....
They are all sham products with no actual benefits.
My thoughts exactly!
As for the chips, you're wrong there. The cheaper chips (ebay) do give you extra horsepower, however I wouldn't exactly trust them as you don't know how accurate the alterations are. Messing with the cars A/F ratio can cause serious damage (cough....detonation....cough) if not tuned properly.
This is why Jet performance chips are the best bet for our cars. It's no different than any other piggyback chips used on other performance cars. Sure I'd prefere a handheld tuner, so I can tune to my own parameters. But when there's nothing else on the market, beggars can't be choosers!
The Jet performance chips are probably more of a "SAFE" tune as they don't exactly tune your car to it's maximum potential. It's more of a canned tune, for widespread use. It will give you some power, but not as much as you could get if you could dyno tune it. Lack of aftermarket support for these cars will make that extremely hard though!
Edit: BTW, maybe oil additives don't do anything, but putting all Royal Purple oil/tranny/gear oil in your car had been dyno proven on video to gain up to 15hp. It was on Horsepower channel, and can be found all over the internet. I can vouch for it as I've definitely gained consistant gains on the track with my Stang after switching to all RP.
