Default My first logs...

A friend helped me do a log on my car. Just left it on while I drove for a while and we did blocks 003, 004 & 115. Did a WOT pull along the line and got these results:

The car is stock except Bi-pipe &amp; 710N's. Should I be worried about the low boost or is that pretty normal for a stock car w/ about 75,000 miles on it?

Thanks for any feedback and I'll log one block at a time next time to get a better sample rate and work on better graphs (unless I did it right already).

Default Thanks for the feedback, I'll do a pressure test. Also, did I do the MAF graph correctly and what

does it tell about my car's condition?

Default Cool, thanks. It looks like it's normal for it to kick in a little late but I need to be closer to

requested on the rest of the curve...

You also may want to try and log one block at a time. You'll get a much better sampling rate.
