Evo 8 intake question

OP Have you check the compression and done a leak down test? MAP did have a lot of issues with that series of turbo, but I would think it should still make more power than that. Either way, check the engines health and go from there. That HP is low. That would be low on a stock turbo.

My timing is nearly identical to yours. On a stock turbo still. The higher up it spools, the more base timing you should be able to run. But still, I would have to go into negative timing (again at peak tq) to go with/or over 26 psi. I'll take timing over boost.

Here is a dyno sheet (if it actually attaches) from I believe the second time on the dyno, it was running stupid lean so we only did 2 pulls I have since put bigger injectors and no longer runs lean I dont have any of the other ones on my phone so I cant put them up at the moment. I'll have to look at my laptop when I get home to see what the timing is set at.

I did a compression test before I started modifying it right after I bought it to make sure it was good:
#1 160
#2 165
#3 162
#4 155
this was with an analog harbor freight compression tester engine warm and throttle open. I haven't checked since then

I get it. No worries. Can you at least say what timing is at redline?

looking at my "High octane ignition map 1" on ECU flash my timing at 7k from load 260-280 is *8
