Load req vs load actual

[GreyNBlueE92]

What tables need changing to get load actual closer to load request? I raised load target but don't understand why I'm only targeting 9 psi at 4.4k, I would like to target 16-17 psi through 5k on stock turbos. Any help is greatly appreciated!

Copied some differences from a SPX map and was able to get load back where it needs to be. I still have a lot to figure out.

generally best to know why, when making changes

What did you copy . ? What boost did you target and what are you reaching ?

I started from scratch and the result was much better. Here's where I'm at now.

Looks good. Pretty much what I did, started with a SPX bin years ago in the Cobb days, then converted to MHD. I even posted one of my bins on the forums.

What is the recommend minimum rail pressure? I try to shoot for 1500+ but recently I've seen low 1400s

One more thing. When I first flash does it take a few runs for PID to figure out where it wants to be? Meaning I shouldn't be basing my logs off of the first few?

As long as your STFTs are not maxing out then 1400psi should be fine.

Filled my tank and now it's 1600+ I only had 2-3 gallons when I saw 1400. Part of having a cracked bucket diy stage 2 I suppose... Better than no bucket...

At what point does the stock inlet/ chargepipe/ diverter valve become a restriction? I hold boost pretty well up until around 5k.

Running stock airbox rn, stock charge pipe, pushing close to 18-19psi midrange. Got my eyes on the 2 inch PR inlet kit with adapters so it's easier to sell when I inevitably go single. Of course it's out of stock....

Also thinking a proper bov might hold boost better up top than my stock dv setup even though it has upgraded o rings with hose clamps for extra assurance. Maybe I'm expecting too much from the stockers. Idk. It just seems like boost falls off after 5kish. Running around 90% wgdc up top.

What is a typical taper at 6k and 7k on stock turbos and stock inlets/airbox? What boost were you running before inlets I guess is what I'm asking. Thanks!

Look at my logs posted here. I taper from 22-23 psi from 4000 Rpm to 14-15 psi By 6000

hehe haven't been on here in a while, cool to see that people are still playing with my old tunes.

Hope no one has blown any engines since I've been off the grid
