MTM chip problems
Just got an MTM chip for my 2001 S4. I like it, except that when I floor it, the tachometer gets stuck at 3-4K RPM and the car lurches for several seconds. The rpms don't go up during this time, and I usually have to let off on the gas just to get the lurching to stop.
Any ideas?

The MTM has a flat spot around 3500 rpm's. Shouldn't be as bad as yours sounds
check your BPV's to see if they are sticking/ripped and your TBB, also MAF, but to some extent, it is something that the MTM just does.

551H or 551M?
there have been some complaints in the past
about hesitation with the 551H software
some have put the blame on Hoppen/MTM's code
and others put the blame on some mechanical issues with some 551H box cars

Re: What is your intake pressure when this is happening?
No, I suspect that this is not normal--my car really bucks up and down the street without any subsequent power surge.
Guess I'm going to to getting some replacement parts!
