Anyone have any good suggestions for a chip for a 98 318ti?
They dont make chips for your car. Anything 1996+ started using a different system called OBDII. The only similar thing you could do is get a shark injector, which really only raises your rev limit without touching your power. Still a very good upgrade!

Makes it harder to pass emissions, how much harder I don't know.
Makes your fuel economy worse. Think about it, your fuel/air rations are being altered to give you MORE power. That's the point of a chip, more power. How do you get more power? More gas and air in each combustion. Why would you get better mileage if you're getting more power?
Most chip manufacturer's claim better emissions and fuel economy..reason being you must use 91 or better octane and like mentioned above the managment is more efficient. Chips also adjust timing so there is more to it than just air/fuel ratios. I also didnt notice and increase or decrease, but after the chip I get on it alot more than i used to, so in that aspect it actually did improve.
