My local shop told me to get the 5bar FPR for the basic K04 package.

The PC-16 would required the biggere fuel injectors and checking things like MAF and such. FMIC recommended but not required.

I currently have the basic K04 chip installed.

 

Did you change your spark plugs to one step colder?

And did you replace your N75 valve?

 

I have NGK BKR7EIX, which is one step cooler. I have not swapped out the N75, but I will try that tonight. I've got a couple of cars to use to swap parts. [8D]

 

Just get a mbc if you end up having to buy a n75 valve... or get one anyway.

 

I've got one, but that may not be the problem. I don't want to treat the symptoms, but the cause.

 

what is fpr s pressure u got on it at the moment 5 bars? it hink not try to change it to 5 bars.u can tell so why dont u change also? but i dont have the exact fpr for my car because my fpr is integreated in the fuel filter the device is like a can.I cannot find it with 5 bar fpr i will drive crazy!!

 

I do have the 5 bar fpr. The GIAC file I'm using is 2001 A4Passat 18T k04-15- 018chk05_K0415_5bar_3X5x_4B0906018.

We're beginning to think it may be an exhaust flow issue, though I'm not 100% convinced. I'm using the stock exhaust, which could be causing backpressure enough to stall the turbo a little. I'm going to use Lemmiwinks to set the max boost (Channel 12) to 85% and see if that clears things up. In stock mode, I have no problem, but I'm only boosting to 12 psi.

 

My car has stock k04 from the fabric anyway yesterday i have changed my chip and fixed my old chip then go to an revo dealer i have uploaded the trial version then go testing and nothing happened!!! i will take the actual chip as soon as possible the revo is not powerful as wimmer but it is working without problem!!Also the dealer said that the actual software will be more powerfull so i will write the comments as soon as i get the revo in conclusion i think my old chip couldnt manage the wastegate as needed

 

I have uploaded the actual revo and everything is ok not so powerfull as wimmer but it is ok
