e85 BEF w/ various maps Trim issues HELP! -
12-30-2016, 12:17 PM
I have several logs that are having issues and I don't know what's going on. I dynoed today and only got 400whp on map 7 2 and 5. My trims were dipping low and even maxed out several times yesterday on 2. NOt sure what's going on I wouldn't keep boost towards the end of pulls boost would just drop off. Running e55. Have all bolt ons aside from inlets and upgraded LPFP stage 2.

Do pulls in third gear from 2k to 6.5k.
The map 5 log showed boost way below target.... only 6 psi even with PWM at max.
The map 7 log showed boost very close to target and holding 16 psi at high RPM.
I would check all the WG vacuum lines and Tee in a vacuum gauge into the WG vacuum line and monitor the vacuum when the car fails to make the normal boost target in map 2.

Boost leak, loose vacuum line on the WG, loose line on the BOV, etc.

Aside from not hitting targets trims and everything else seems ok even on map 7? Any suggestions to keep ic connections from coming loose same for vacuum hoses. Thank you guys for your time to look at them. I recently did a map 2 pull after going back to race flash and it seemed pretty consistent.
