Hello everyone,
I’m new to spoolstreet, I’m currently replacing my lowpressure sensor right now but I did a log a day or two ago and was wondering if I could get some feedback on how things look?

I would also love any pointers as to what I should be watching for in my logs and measuring/looking at on the regular? Thanks in advanced!

You should probably spec your car, what Mods are installed, what tune you are running.

Only thing I noticed was your IAT's climb pretty quickly. Stock FMIC or 5"?

Absolutely, I apologize.
3” Catless DP’s
DCI
Charge pipe/BOV
NGK plugs gapped(they’re old and fouled in that log)
Eldor coils <9k
5” no name intercooler so definitely could not be the greatest for air flow, need to get a 7”

But everything else looked ok and within good spec? What are some key items to look at? I normally keep rail pressure, lpfp psi, IAT, boost and target boost, and occasionally I’ll swap out for all six timing corrections.

Thanks a lot, been a tremendous help! I think I’ll just flash a stage 2+ via MHD for now and work on replacing my lpfp.
Do you think my rail pressure/high side looks good? I’ve been told upgrading lpfp helps with rail/high side as well, true?

True, until you push more boost / power, then the hpfp will tap out and you will need auxiliary fueling/ overdrive kits/port injection, etc
