DFM

[jettech]

For all everyone who has already received their ZR2 haw does the truck feel with DFM? Is it noticable, does it sound weird, how's the acceleration?

My 6.2L Trail Boss has it and it's not really noticeable with stock exhaust. If you change your exhaust, it's more noticeable. The louder your exhaust, the more you will notice DFM.

Even with a louder exhaust it is exhaust it is no big deal. I strangely kind of like to hear the different sounds. Acceleration is just like a non-DFM. DFM more kicks in downhill or when you let off the accelerator to slow.

Anybody get a strange whistle noise when DFM is active just cruising slowly or at cold start?
