Did a compression test today, drivers side were all evenly at 135 passenger side were all evenly at 150.

Looking to do boost haven't done a leakdown test but from these numbers can someone please share some input?

Numbers look good. Is that all you were wondering about? Your question was kinda vague.

Basically just wondering if I have a healthy engine on my hands. I did a retest on the drivers side. Numbers are 150 even. Fitting issues on the tester.

You should be more concerned with variances between the two or an outlier. 150 is within acceptable range. The fact that all are the same means your rings appear to be wearing evenly. I say good to go.

just want to make sure before Install, I'm going turbo with plans of running 8-10 psi. I've yet to do a leakdown test but after pulling plugs and seeing they all wore evenly with normal wear and the compression test I'm pretty confident I can run low boost. Gonna be a wicked ride
