This new MSD intake he is trying is not a stock Mamo ported MSD. It has been extensively modified by another "porter"
Oooooh ok. Maybe the new motor in the TB is bad, most of the time the big power ZR1's are the only ones sucking the 108 closed.

Possible a bad motor, but it was a completely new throttle body and motor and apparently worked fine when tested on a LS3 build (I think is what JayyyW)

it was a mamo msd thrn sent to some other person who went to town on it. So saying this is a mamo msd is not even close to accurate. He should have stuck with the mamo.

It's not the same TB. Jeremy bought his from another source.

Damn, that kind of sucks. Does it feel any different? Did both graphs overlay on each other?

Yes, he's back to generally the same power.........675+ on the last pull is what he told me this morning.
The 102 tb is not the limiting factor with the MSD intake. When we finally test the new FAST, I suspect the 108 will show some minor improvement.
