ECU Remap Chips That Really Work?
 
This is a tough question as typically it garners responses that are mostly guesses without any real evidence one way or another. By evidence I mean, someone actually dyno tested the difference any chip might make in power and torque. Not, it "felt" faster, or "I heard these were a scam." It's widely known stock ECU programming is conservative. If you have a car programmed to take 87 regular octane it's common knowledge you can increase horsepower if you use higher octane fuel and advance the timing (and alter air/fuel mixture) as the higher octane fuel will not create engine knock when advancing the timing and you'll get more power.

Now the $20 chips on Ebay I would say, you get what you pay for (practically nothing) but what about the $100-$200 chips that plug into the OBD2 port? Are then really any different than the cheap Ebay models? I've also seen chips that plug into a sensor under the hood and others you splice in.

Wondering if anyone has found a brand that is reputable, producing products that actually give you some real gain in HP/Torque (like 7-10% or more) in conjunction with running premium gas. Someone that's either done a before and after dyno test or before an after with a performance meter like a Passport GT-2 or can point to reliable information backing up your claims.
