LNF K04 Forge VTA Tune Requirements
What needs to be taken into consideration in the HP tune file to use the Forge or Turbosmart Vent to Atmosphere diverter valves?
I plan to install one and want to know if it a couple simple tweaks I can do myself via HPT or if it is more involved....

I ran the FOrge one for over a year and a half with no issues, full VTA with just my HP tune from Term.
It went rich on shifts, 10:1 afr, and that was the only downside. However randomly it decided to throw p0101 cause the damn thing was staying open too long, therefor throwing me into limp mode.
If you want to do it right, buy ZZP's lower CP and do a MAF relocate.

Yeah I never needed it til it was staying open and I believe that was due to my own error with routing vacuum lines.
However, once I relocated my MAF it was 10x better.

Except you should not shut off that code as it indicates boost leaks. Relocate the MAF. Did you want me to fix your tune for you?

Is the MAF in the intake stock and needing to be moved into the lower charge pipe?
Yes, I do. As soon as I get paid I will license my car and pull the file. I forgot about floridas awesome new wheels tax and spent an extra $300 on registering it.

unless you do a maf relocate your not solving any issues as far as the rich spikes go. recalibrating the maf isnt the easiest thing unless you have done it before. at that rate i would buy a good blow off valve like a tial(especially if you plan to do something other then a zfr in the future). Sure its more expensive but i feel its superior and sounds better.

I wanted the Tial, but I got an HKS for too good of a deal to pass up. It actually works very well, and closes much better than the Forge unit did. I had to use the Yellow spring with the k04 and I was going to swap to the blue spring with the ZFR.

I may be guessing, but if I install the Forge now and decide to go with a BOV later, cant I just put the stock BPV in my turbo and have Josh put the flange I want on? No retune needed because everything was already done for the Forge VTA?

People have done that. I just got a blockoff from Treadstone for 30 bucks. You will need a retune once you swap the MAF to the lower CP. but once that is done, you wont need retunes for BOV.

Like others have said, relocate the maf without question. Otherwise it's far more of a headache than it's even worth to run a vta dv or bov.

^^ This... and regardless of that possibly happening, relocating the maf is still really the only viable option for a vta dv/bov setup. It's far less of a headache to periodically clean the maf (which really should be done under normal circumstances anyways) then it is to deal with the nonsense of a vta dv/bov in a draw through maf setup.
