| I say chip it!

| I just purchased the Shark Injector ($349) for my 323i and it seems to have made a noticable difference. It's not drastic but it's there, and it was easy to do. So if I were you, I'd chip it. I'm happy with it. PS - Sway bars for the engine huh? I'm learning something new everyday ![]() |

Tom330idriver, i say you either get a dinan chip, or underdrive pullies. you'll notice a difference with both.

| Copy and paste right from UUC site - What's an underdrive pulley? An underdrive pulley is a replacement accessory pulley that bolts up the same as stock, but has a different size (ratio) and material specifications intended to free up lost horsepower. By increasing the diameter of each accessory pulley, the speed at which the accessories are turning relative to engine RPM decreases. Does this actually make horsepower? Underdriving the accessories does not add power to the engine, it frees up the power that is normally wasted on overdriven accessories. The theory is that a larger pulley will drive the accessories slower thus reducing their parasitic horsepower loss. No more power total, but more power sent to the wheels. As an additional benefit, the reduction in wear (less usage) on the accessories due to the lower duty cycles can extend the life of these parts.
