  • here is something for you guys

    I can go past 80 miles per hour quicker by putting only 1/4 or 1/3 gas down not hitting max boost and not using the wastegate

    When I do 100 percent down I creap along past 80 real so like hitting max boost and using the wastegate. Now reading over vipers litting thing....can my wastegate be dumping too much which causes less air to go into the intake and doesnt allow me to move quicker then I do at 1/4 throttle down?

    I'm guessing the engine isn't getting enough fuel. I had the same problem with my car and after I upgraded the injector to the 36# ones, I can finally floor it without it going lean.

        At 1/4 or 1/3 throttle, your PCM is using the O2 sensor in a closed loop mode thereby adjusting the A/F ratio to 14.7. At WOT (Wide Open Throttle) the PCM uses a look-up table instead because it is trying to use a richer A/F ratio that is beyond the measurable range of the O2 sensor.
        Do you notice a sharp decline in power when the throttle reaches at certain point or is power at WOT good until your reach a certain RPM? The answer to that question will point you to whether you should look at a fuel delivery problem (Liters/Minute) or a fuel management problem (A/F Ratio).
