OK....We all know that autos rob more HP the manuals trans. That is a given. Everybody quotes the estimated % that is widely accepted. But has anyone ever dyno'd before & after, with no other mods? I'd like to hear from more than just 1 person, to get a broader sample & compare #s between people.

Anybody?

It's not a straight percentage.
Auto tune cars can take more timing advance so it wouldn't be an apples to apples comparison.
Just food for thought.

Yes it is (can be). Just swapping trannies & not changing the PROM or tuning. What would someone get?
