Wookiee Fury Posted January 20, 2015 Share Posted January 20, 2015 I did an E-tune through Cryotune and finished up in June of last year. I had an amazing experience and 0 complaints. I periodically check the LV and never noticed anything odd. I just checked and one of my Airflow Ranges has changed signficantly. I have included the last LV of the E-Tune and the current one. What are the possible causes of this? Link to comment Share on other sites More sharing options...
fahr_side Posted January 21, 2015 Share Posted January 21, 2015 If the one with all positive trims is the post-tune LV, and the one with -11.xx in range D is now, you probably have a boost leak.

cryo Posted January 21, 2015 Share Posted January 21, 2015 yup, I would say you sprung a leak. Check all the common causes and I'm sure you will find something amiss.

xt2005bonbon Posted January 21, 2015 Share Posted January 21, 2015 Have a good look at the TB hose. They are notorious to leak with increased boost level http://www.legacygt.com/forums/attachment.php?attachmentid=81853&stc=1&d=1268677668 Link to comment Share on other sites More sharing options...
Wookiee Fury Posted January 21, 2015 Author Share Posted January 21, 2015 Thank you for all the replies. I looked last night and I think that hose might be my problem. I think mine looks a little different. That is the one coming of the TMIC, correct? I took it into the dealer and neither the part desk clerk nor the tech could tell me what part number it was so they could order it. They said it MIGHT be an $80 part. I don't have much faith in the dealer anymore. Link to comment Share on other sites More sharing options...
fahr_side Posted January 21, 2015 Share Posted January 21, 2015 Most of the time, junking the two soft couplers will fix this issue. If not, aftermarket silicon item.
