2000CL713 Posted December 28, 2017 Share Posted December 28, 2017 so this low boost issue i have still continues. i had a boost leak down test done today and nothing was found. im only seeing 27lbs (maybe 28lbs at most) with the truck loaded shifting at 1600-1650. i have a 460xt program on truck (2000 CL713 E7-427 dump truck). no codes other then a 8-5 code (electronic unit pump #5) that showed one time back in oct and its never happened again, not sure where to go from here. depending who you ask i should be in the 32-34lb range.

2000CL713 Posted December 28, 2017 Author Share Posted December 28, 2017 iv owned the truck for about 10 years. i cant recall if its been a problem since i have owned it but its always been little lower on the power side of things. when i added the XT program few months back it waked it up alot but it still shows im low on boost as per the gauge.

Mackpro Posted December 28, 2017 Share Posted December 28, 2017 Can you read the number on the tag of the turbo? Should be like a 631GC5145M . If not , give me the number and I can pull it up and see if it's the correct one Quote Link to comment https://www.bigmacktrucks.com/topic/52065-low-boost-but-no-boost-leak/#findComment-388396 Share on other sites More sharing options...
