Is there an advantage to putting the O2 sensor behind the X pipe to get a blended reading of both headers?

That’s a trade-off! While you would get a blended reading , the X pipe is far back in the system and would not react quickly. We find that one collector works fine and gives instant readings and fast response to... Read More

How do I change the MAP sensor for BOOST?

You don’t need to! The ECU is equipped with an onboard 2.5 bar MAP sensor good to 25 psi.

Why are your systems so inexpensive?
