car was just recently chipped and every since last week has been having very violent hesitation issues under hard throttle...anyones advice on this issue would be great...is it software related or just something that happens when part of the car isnt up to par??

did you do a throttle adaption when you installed the ecu?

Fall on it's face while accererating (Dat would be limp mode). Often chipping brings out the weaknesses in other parts that were already on their way to Audi heaven (Like the MAF)

off. I was also blowing clouds of black smoke out the back of the car. Something about the MAF reading the mass of air and the air never making it to the cylinders, but the fuel was still sent... I managed to get the hose back on for my next session...

the maf was checked with a vag while i was getting chipped, its brand new and working great. im not sure if a throttle body adaptation was done. also i was told that i have a boost leak between my turbo and throttle body. i just want to check that the issue im having is in fact the boost leak, because i dont want to mess up while pressurizing the system. i did make a pvc pipe + air chuck and have an air compressor. should i go ahead and attack it or get a vag first and look into other problems such as coilpacks?

seems its the hose that runs from the n75 to the wastegate, on the wastegate side. i had replaced this hose with 1/4 vac hose due to cracking. i guess i didnt clamp it down tight enough...
