I am happy to find my Lincoln "certified" used mkt is finally running better. we bought it 2 weeks ago and it seemed sluggish.....they gave us a loaner mks for a few days for some warranty work to get done...seemed a lot faster.....dealer said ours was fine....long story short I installed all the basic stuff you guys do for a 3 bar tune(live wire ts, map, stat, airbox, etc.....boost showed low on log...(im just learning the software) Torrie says something is leaking or mechanical....I go out after lunch and find bank 2 wastegate linkage is off and e clip is gone....so I fix that and now we can move fwd. now I fell better!! thanks unleashed and forum
