    High voltage on the O2 is usually indicative of running rich which is evident by the other codes P013A. The second code is telling you it has made an attempt to lean it out but the car isn't...

    I ran one at 3 bar and 55-60 lb/min. Its within the 75% efficiency range and max rpm at 3 bar is way out at 68 lb/min which is like 670 hp equivalent according to the map. Most people aren't making...

    the early oil pressure sensor is a 1-wire sensors that is not compatible with most new gauges that use a 3-wire sensor. Wiring a 1-wire signal into your aftermarket gauge is not likely to work. If...

    Its all about accounting for pressure differential changes. (rail pressure vs. manifold pressure)

    The phenomenon: For this example assume the rail pressure is fixed at 58 psi. If your at idle with...

    I didn't catch that comment about not wanting to tune fuel.

    I don't know about slamming the gaps to .023" right off the batt. If the pressure is lower like 10-15 psi then .032-.035" is probably enough. High rpm breakup would be across the board and that would...
