This is either not 2byte load, not 25psi, a boost leak, or you have a intake that is seriously messing with the readings

 

Sorry for the noob question but I have been using load to 'regulate' my boost. I figured it was a good way to do this - since I have a 'boost' guage but everyone says they are not that accurate. I'm currently running 280 to 260 load values from 4k to 6k - then taper to 220 by 7.5k. I run 91 gas and have the timing pretty safe as well as the fuel cells (translates to NO knock). However, I'm reading this thread and noticing...that people have different boost numbers to their load numbers...why?

Side note - I have been working my tune this last week and am currently bringing my load numbers down to 270 and staggering down...but should I be concerned?

Thanks!

 

^^Different boost versus load numbers because, as you said, they may not accurate. :-) but we can statically approximate them using the common numbers like in this thread.

 

I primarily drive around with a 100 octane open track tune. I am stock except for an ETS FMIC, EBAY TBE, K&N Drop-In, and a Tune. This is what I see when logging a spike to 25psi and an attempt to hold it to redline:



It varies a little as I row through the gears:

 

i just did 320 load on the way home

93oct
21psi

 

I'm betting that 320 wasn't reached at 3500 rpm though!

On the stock snail running 100 WDC on C16 I can hit 300+ but that is just not healthy for the turbo or the head gasket!

 

pretty darn close to it

 

Steve, leave your load numbers alone. On 91 octane, I hit 2byte loads between 290-300 peak with 23 psi tapering to 20 by redline. My numbers are very similar to razorlab except that he holds more load by redline.

 

IX turbo, 93 oct (E10), 24 psi tapering to 20.5 psi.

Small spike to about 275
Hold ~258
End at ~225 at 7300 or so

 

^ That is what I see with my race gas map. What kind of timing are you running.

 

That is pretty much how mine is as well with same boost, turbo, and fuel

 

~11.3 AFR to 11.1 AFR at redline
3º peak
13º at 7300

I haven't logged in a while ... this is top of head.
