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
