hey there i have 99.5 a4 quattro with a k04 turbo on it recently i had my mechanic rechip the computer from mtm, i am running at 20-21 pounds of boost with no problem the computer is satisfied and is running the boost. I have not had one code and or cel light but the car will still studder and hesitate when i put it to the floor in 5th gear, i don't know what else to check i have a 5 bar fuel pressure regulator and have checked all spark plugs and coil packs and don't know what else i should do. any suggestions would be great thanks.

why did your car need to be "rechipped," are you sure MTM calls for 5bar fpr, and how did you check the plugs?

i had the nuespeed software in the car and it was really slow so i got the mtm software, the software requires a 5 bar fpr. I have replaced the plugs with a hotter burning plug and checked all the coil packs, they look good i replaced one of them that looked ok just to test it and still i have the hesitiation. But i just can't figure out what else to check. Thanks for any help

what rpm in 5th?

Tuning is load based. Most likely you are in max load causing the ecu to run too rich which then causes what you feel. Might want to try doing a log of 003 and 031 together while causing the issue.

i have a '98 30v 2.8 and my car does the same thing? not on boost or anything idk, its in the shop right now getting fixed, hopefully...

could be your clutch slipping. that would cause a stutter.

i just replaced the clutch, and the more i drive the car the more i feel the hesitation, i can feel it in 4th and in 3rd sometimes, it's almost like i'm not getting something but the boost is holding strong......so can't figure it out. thanks for all the ideas please if you have anymore let me know thank you very much

maf maybe since it seems to be a load related.
