yeah they only made it for 2001+ and then dropped the 2001 so they only have it for the 2002+.


Do you have a vagcome? IF you do log block 003 or block 054 duing a 3rd gear pull or when you have the issue.

 

yes my problems only seem to occur above 17 psi with the mika chip. The apr ecu does all kinds of surging and misfiring when i try to open up the throttle becuase the boost just jumps up and down it seems.

 

i do not have a vagcom but i plan on taking the pain and bringing it to swift motorsports to pay to have it fixed

 

ok so just for reference i figured it out. I fixed a vacumm leak and it didnt solve anything so i figured what the hell ill gap the plugs to .024 instead of .028 and bam. Power back smooth as butter. Just incase someone else runs into a problem like that.

 

Yeah that is too small of a gap which means less spark and less voltage used. Larger gap means more resistance which in turn means more voltage.

You reallly want to start with a gap of .032 and only make it smaller if there is a misfire issue. Even the pre-gapped bosch F6DTC plugs come with a gap of .040. I run those in my car pushing 37psi.

 

i understand but at .028 on ngk bkr7e's the misfiring is nuts and it wont accelerate btu with .024 its scary fast. So bigger in my opinion would make it worse than before. But ill try it out.

 

Well the thing is that our ECu controls the amount of voltage used, increase the resistance of the spark the voltage goes up. At that point the only thing to cause an issue is spark blow out. Go too small of a gap and there just isn't enough spark to burn all the fuel. This is why the range for normal single tip gapped plug tends to be between .032 and .028 for our A4's. Always best to start big and work your way down.

 

i tried big and nothing. I think this might all be related to a bad fuel filter or pump. My buddy had the same issue and it was the fuel filter. Maybe at .028 there wasnt enough fuel and it was burnign it all out but at .024 maybe it just balances out. So im gonna try checking the fuel filter and get a high pressure pump and adjustable regulator

 

You are still running a stock pump on a stage 3+ setup? The stock pump cant move enough fuel for a GT28rs or larger turbo. You need a walbro or a bosch 044 pump.

If the fuel pressure starts to drop on your 2000 the AFR will go lean.
