I recently started a thread on here about deleting the boost a pump Hobbs switch from my 2.6H Kenne Bell Cobra. The intial results were great, the car felt like it pulled through the rpm's much smoother! Well not too long afterwards, my car started falling on it's face when I would put the throttle under load during low RPM situations. Once I get past a certain RPM it pulls smooth like normal. It's only at low RPM's, or between shifts that it cuts out. What do you think could be causing that low RPM stutter? The PPRV valve? Do I need to do anything with the voltage twist knob on the boost a pump? Do I need a new tune now that my boost a pump is working full time now? I wired the two wires together that went to the Hobbs switch so that the boost a pump works as soon as I turn on the ignition. I can hear it buzzing whenever I turn over the ignition key before I start it up. Any suggestions of what could be causing this would be great, thanks!
