[DeTomaso] Engine Noise

[Kirby Schrader]

Charlie,

Yeah.... I _was_ kinda' bummed. Rumpity-rump cams sound cool.
But the lumpiness went away mostly due to the IR intake.
Not specifically the EFI.

But the low and mid range performance increase was well worth some  
lumpiness loss.

:-)

Regards,
Kirby
