    Yes setup I would run 60 but it ultimately depends how many rpms you plan on running. More rpms' more fuel

    I run one earlier this year on Bosch 55 and it worked very well. Your AFR's will be very rich in the lower rpm range unless you are going to us a fuel controller or a begi set up. Make sure you are have an AFR gauge. A Rude3 will burn a piston out is seconds if you are running lean.

    I have yet to choose an ECU set up so thats still open.

    Am thinking of going the CMD route with RRFPR & Begi if needed plus all the normal gauges and a few more for good measure!

    I like the idea of being able to monitor everything in real time including exhaust gas temps - How is this best done on a 06 RXP - It will be running a 09 manifold, waterbox and midpipe thats been modded and a rear exhaust setup.

    If you are going the CMD route , you will not need the rrfpr or begi. Use siemens 80lb injectors and use cmd to take fuel away.

    Ahh that's good to know, some money saved there then as I don't have a begi yet. Thanks.
