Newbie question here I have a 2010 Jetta that has a Malone stage 2 tune, egr, cats, dpf, and wastegate all deleted and replaced by turbo to factory muffler straight pipe. It has been 85k since I did the mods with no problems until now. I didn't drive the car for two weeks and it started right up but when I left the driveway it has little power and rpm stops at 3000. I can still here turbo whine and it runs smooth. Changed fuel and air filters and unhooked the maf sensor with no change also tried cleaning the maf but no luck I'm out of ideas and could use some advice and the car was running perfect before it sat? Thanks for any help

Best to start with data logging, might be boost control, does it go into limp mode after awhile or just slow right from the start? any codes?

It has been in limp mode since the trouble started it idles fine maybe alittle extra diesel smoke but not rolling coal or anything it's just making very little power and I can't get it to go over 3000 rpm either driving or reving it in neutral. I will look into a data logging. I have to go out of town for a couple days but will do it as soon as I get back thanks for your insight on the problem you guys are great that's what I call customer service!!!

When I hook it up are there some specific parameters that I should be paying more attention to than others?

While you're in there, might want to rule out the dumb stuff. Damaged wiring, loose piping and rotten vacuum tubes.
