Hey guys, I am new here and want some advice. I did a compression test recently and my results were 215-220 all around. Is this safe to boost and why is my compression so high on a 128k mile motor? Also wondering what wastegate and bov you guys are running on your turbo de!

 

If they are all around the same you are good. Probably a gauge issue
I did not do a compression test on my 145k mile DE before boosting
Emusa wastegate
Type-H bov
