Stand Back only boosting 12psi?

[steven88]

- CP-E StandBack with PNP Harness (not running toggle switch)
- Standback Software Tuner V2.59D
- Everything on the tables zeroed out
- Check 17psi on box under the CONFIG SECTION

Advanced Boost Control

KP = 30.000
KD = 100.000
KI = 00.090
Boost Clip = 13.0
Map Filt Len = 05
WG Filt Len = 09

Fuel Cut Settings

Fuel Restore TPS = 1.00
Fuel Cut Volts = 1.50
Min Map FC Enable = -04.00
Fuel Restore RPM = 2000
MAF Volt Clip = 4.90

Btw, these settings above are default settings for V2.59D

So I am only getting 12psi according to my dash hawk...even though I set my boost control to 17psi on the box and not the tables...I have all tables zeroed out...I do not have a boost leak anywhere because when I removed the SB + PNP and ran stock ECU, I get 15-16psi all day

Any suggestions?

The Map sensor may be clamped (to prevent boost cut), this would account for the inaccurate readings on the dash hawk. See if you can locate someone that can lend you a boost gauge just to see.

yes you need a boost guage to accurately read your boost levels with the standback.
The dashhawk is reading only what the ecu thinks its running at ie 12-13psi what the boost clip is set at on the standback

(to the OP) Not to sound like an ass but how can you NOT know this?
