Hey folks, I'm looking to increase performance of my 328is (currently stock). I'm looking at CAIS, Conforti chip for starters. I also heard that disabling the elect. governor will add top end speed. Is this true ? Is it computer program related or is it as simple as adding or removing a resistor...not sure...looking for help. Also would like to know if anybody has experience with the low cost CAI systems listed on Ebay. There are several different styles...but no matter what, $20.00 to $30.00 seems cheap (and a good way to go if they're worth it) compared to $300.00 for a similar Dinan set-up. I'm guessing it's the "you get what you pay for" thing.
