      Can anyone share some insight?

      Car kinda had a wonky idle. Sometimes it's high. Sometimes it bounces. My biggest issue is while driving normal and "feathering" the gas to maintain speed it's a little bit unresponsive for like an 1/8th throttle.

      V1 charger
      36# tune from c2
      6puck sprung clutch(not sure if that's even relevant)
      Stock Audi a4 diverter valve

      I leave for sowo(13.5hr drive) would like to work this out

      Only thing that might change this also is the vacuum line on the throttle body is plugged. Not sure if that matters at all.

      what boost are you running?

      you can calc the CC´s of the injectors 1:1 in horsepower.
      so 440cc @ 4bar will be ok for nearly 440hp

      its a stage 3 kit vfe says it will do 300 whp @ 10psi, so 300cc injectors? seems small, i will be running 4bar

      300whp?
      Not to be a negative nancy or anything, but I find that extremely unlikely from a vfe kit (or any standard V9 kit).
      Many here will agree that VFE is pretty shady when it comes to VWs, and they like to stretch their advertising a fair bit.

      300hp at the crank perhaps. After drivetrain loss, it'd be about 260-70whp.

      edit: their own graph for stage2

      looks like 250whp & 230lb-ft, compared to their advertised 280hp 250lb-ft for stage2

      add maybe 10whp per psi (their stage3 is 2psi more)

      250whp requires more than 10psi. On stock cams its more like 12psi. With 268 cams, 12psi and a good solid tune 300 is a lot closer, however it still is very difficult to go much over the 300 range as the ability of the belt to transfer drive torque is being overloaded at that point.

      for over 6psi you need 30# or 36# injectors depending on the software. The 30# C2/UM file sucks the big fat one. If your running 8psi on GIAC, I suggest staying with that. The allowance of power and more boost with C2/UM is at a trade off in driveability and engine life. C2/UM runs way rich and will wash down the cylinder cross hatching.

      Only way to go is Lugtronics/other standalone.

      ruf and me designed a new impeller wing for the rsc charger. it now pushes out 13psi. should be enough for 300hp on a vr6 engine. the main problem will be the cooling with a standard fmic. the pressure drop is to big so we only use liquid intercoolers for supercharged cars. maybe this will help the Vx chargers to more boost.

      we tested it on an r32 mk4 with a 9,5:1 compression. it made 370hp. ill post the dyno later

      I think that had some to do with your setup, i have 3 c2/um tuned supercharged VR6 cars in my driveway that run and drive great, 1 has 157k miles on it and has had the c2 tune since 07 when it had 115k, 1 with 113k and no issues had the tune since 90k ish, another with 171k and no issues aswell, the head was just off to do a 8.5:1 spacer and upgraded to 630 pro maf setup and the block looks great.

      donno why you runs such big injectors. you can go with green g60 injectors (280cc) @ 4bar to get 270hp. maybe its the better fuel in germany? i run 470cc@4bar on my v5 gt3071r setup with 1,5bar boost

      much better fuel in germany
      for the most part, the best you can regularly get in north america is 94 octane which is weak compared to the 100+ you can get in europe

      hmm.. curious! in fact that you have to calc the boost on top of the fuel pressure. so when you run 4bar fuel pressure + 1bar boost... youre already at 5bar fuel pressure. cant imagine what stressy job its for the programmer to get a stable idle on such cars

      102octane? we also got e85 gas stations now

      Isnt that what the whole new fad is with the rising rate fpr? The fact that its linear and easier to tune for, yielding higher numbers..

      as long as the fpr is on the (under)-pressure line it will ever be the same
      so an original fpr will raise fuel pressure with rising boost.

      Rising rate FPR's = Junk. A bandaid fix that should be solved with standalone.

      i think the wording is getting people all confused. A regular FPR will raise fuel pressure 1:1 for boost. What you want to stay away from is 2:1 4:1 12:1 etc. these are usually called FMUs.

      correct but in his opinion they are trash too
      if he wants a stable fp, just pull off the pressure line

      Rising rate FPR's was how EIP use to tune, increasing fuel pressure on stock or low flowing injectors until they flowed. IE to the fuel pressure levels of CIS cars. But that was perhaps before your time.
