About 3 years ago I put a quad pod on my 96" (Thank you Paul Rutledge :jammin
and at that time took notice of the extra brittle condition of the MAP (Boost) line. Instead of cutting, it pretty well broke in half! The gauge worked so I never replaced it.
A year ago I began to notice a loss in power, and the boost gauge would only hit 5-7 psi where it once would hit 15. I just chalked it up to 300+ k hard miles and carried on with the thought that I would someday be replacing some injectors and adding a 17+* HPOP. In the last 6 months it really began to fall away and the boost gauge quit moving completely. Now designated DD work-to-home truck I began focusing on MPG and completely forgot about ever pulling with it again. A couple weeks ago I swapped the 4.10 rear for a 3.55. and the truck became a slug, might as well have been IDI.uke:
Over the last week I've been talking with members about injectors and an HPOP. Monday on a whim I decided to try the race file on the TS chip and it came back to life! :wtf: After talking with a member today and bouncing some ideas off him I decided that the chip had gone bad or was not making good connection.
For whatever reason it was today that I remembered the brittle MAP line. A stop to a local parts store and 2' of air hose later I popped the hood right in front of the store and saw my boost line burned in 2! Pulled that and pulled on the MAP line which crumbled in my hand, replaced the MAP line. Startup instantly sounded better, thinking it was just in my head i proceeded to the grocerey and stabbed the pedal a few times and barked the right rear tire!!!!
The power, all and more is back and the boost gauge is hitting 15 again.
It runs better now with the 3.55's than it did with the 4.10's. Leading me to believe that the danged MAP line had been giving bad signal from the day I bought it and just got worse til it was just barely working. $1.98 fix.
