[ronnies88]

Its a 91 awd eagle,runs pretty good during normal driving,does not pop or anything like that just feels gutless 19lbs of boost,I have a data logger what to look for?????

 

[erald01]

Any boost leaks that you might think off? Are you getting boost spike?

 

[ronnies88]

19 lbs and holds it what about data logs what should I be looking for like tima o2 voltage and I get 43 counts of knock random.base timing set at 5 degrees Im about to pull my hair out

 

[erald01]

[ronnies88]

Definitely do either a compression test or leak down test.
