7mgte raising compression questions?

[shaeff]

Hey guys. Look at most aftermarket forged pistons specs. They're _rising_ CR. The only pistons _lowering_ CR a bit I've seen are probes.

Huh?

so would the consensus be its okay to bump up compression as long as i tune? lol because i plan on going with a standalone aem later on becaus lke i said i would like to get some more bottom end response but also be able to spool a decently bigger turbo.

Huh?

I meant Arias, Wiseco etc. off-the-shelf pistons for 7M.

It's kind of up to you. Bumping it up 1/2 a point or down is not going to make a huge difference. For me personally, I like to get as much off-boost response as I can while trying not to cause too much knock on pump gas. If you are more concerned about knock then leave it 8.4-8.5. Going from the stock 8.4 to 9.0 compression is not going to turn your 7M into a 6.0 liter V8, it will just give a little tiny more response down low.
