I'm an Accel dealer, hence the reference to my video on their website.

But there are other good systems out there, i.e. FAST XFI etc.

My point is the aftermarket mass flow systems are good for mild to moderate applications but beyond that they are severly lacking.

And unless I have some bad info the MassFlo/EEC-IV only allows 20 degrees of timing adjustment as well. I have a 350 Olds that has about 16 degrees of advance at idle and 42-44 under cruise with my Gen 7. Do the math, can't do that with their system. Nor can you compensate for temp on the advance side either, more when cold, less when hot. Can be a significant drawback.
