I have. Bought a chip for a 2.4L 2007 Toyota Camry LE. I installed the chip and noticed that the acceleration lag my car had became a little worse. Figured maybe because the chip was tuning the engine to run leaner. However, after comparing my fuel mileage for 500 miles before the chip and 500 miles afterwords I found a loss of just about 2 MPG. I uninstalled the chip, did a new baseline of 500 miles. Then re-installed the chip and did another 500 miles with the exact same results. Basically, I noticed no increase in power from the chip... if anything it reduced my power. Basically, you'd be better off spending the $50 the chip costs on a tank of high octane gas and some engine cleaner. You'll get better results.

I installed a tunesport performance chip on my 03 Hyundai elantra, and noticed decent results. On another note though the wires came loose on it eventually, i took the casing apart to find they weren't even sodered,but glued on. I sodered the wires properly, re-installed the chip. The results after fixing this problem were remarkable!! I'm guessing at least a gain of 50hp!!!

I recently bought one of these chips and I made the mistake of looking at the reviews after I bought it, I popped open the "module" and all that's in there is a half ass glue job and a piece of metal, no software at all.

i want to buy one but am having second thoughts based on reviews. I am currently driving a 2001 jeep grand cherokee 4.7 v8. SO are they a scam? or do they work? is there any software to them? or just a fake piece of plastic?

I just opened the Chip one of the wire were not connected that is why the chip won't work; but of coarse I have not tested it out yet to scared that I may screw the car up again. Anyone who has this chip open it up if both wires are not connected to the chip it will not work.

My car never lost any power are acceleration neither gained or lost anything. So I got curious and opened and found what I thought in the first place. Is the chip worthless can't say, Just that both wires were not connected to the chip.
