There is a loud pop coming from behind the dash on acceleration, hard or soft, anyone else experience this? If so this is annoying and i want to pinpoint it. Thanks

it is probably just the full pressure HP solenoid you are hearing. It simply adds more hp when needed on accelerations.

Can it be felt in the brakes, through the accelerator or in the steering wheel? Is it a "thump" and possibly a U-Joint or CV joint "thump" on take-off?
