Is this normal? It seems like my boost is only 1-6 psi. I thought it should be around the 10-16+ range?

Something doesn't look right, especially if you're only seeing those boost numbers. That log is hard to read though.

Try to get a log of only 3rd gear across the entire RPM range.

My guess would be boost leak somewhere, do you have any codes?

I'm not throwing a single code. Am I right that it should be much higher? What other parameters should I log to give you a better view?

This map is not working well with your car. Lot's of throttle closer. Boost solenoids could be weak. Vacuum test them.

Alright I have a new log.

I didn't change the map, but I did do the Solenoid bypass mod on the rear solenoid (thinking it would be helpful until I can get my hands on a vacuum test gauge and kit). It looks like my boost levels are much higher, going up to 12psi in some cases. Do these look better or correct?

Also, in about the middle of the graph I actually tried to start in third gear. Difficult but I wanted to see if it showed in the graph going up to about 6500 RPM.

I'm going to either have a shop do the vacuum test while I'm there for something else, or try to buy all the parts to do it myself.

Would this writeup be a good one to follow? Any others?

Hopefully I can get to the bottom of this before I go and spend $300 on new solenoids.

So I'm looking at the chart and I don't really understand what some of these mean, but I see a "req. boost" and a "boost mean" and a "boost" What do these mean?

I'm assuming it means the requested boost from the ECU and my Actual boost? Which is SIGNIFICANTLY lower than the requested boost.

Req. Boost = 25.59
Boost = 9.32

Am I reading this right? I should be pushing 25psi and im only pushing out 9psi?
