Turn down the boost, 170 psi is a lot.

Yeah more info on what the values are would help reading it.

What are you using to tune the car?

Boost seems to fluctate alot seems like the turbo is being pushed pretty hard or the ecu is trying to pull boost down to help prevent knock.

That torque graph is all over the place def a very bad tune

lets see here
main point is hugh hole where knock is

tec2 -dyno log lab
afr ..mid 11s.. is difficult to tune and drive need to make op amp circuit to log wide band afr (the only way with a tec2 and lm1)
boost mbc ball/spring
actually not sure what the proublem is the blue line is timing i know i am not running enough at the top end most of the flat line is 9deg thus the HUGE drop off at 5500
was also ~20deg F outside when i made this run

this is my first real expirence with dynologlab
getting a good overlay like this with standard tec logs is difficult

9 degs?? Knock from lack of timing?? lol That is a sad timing map. Dip in power just doesnt jive with other data recorded. A knock event alone wont cause that kind of power loss, and it didnt pull timing(not that it could run much less then 9 degs)

EGT'S? My guess is very hot!
