Shiv has adjusted the torque/boost settings to come up with a "DP map". No need to have V3 for that.

No stable map for DP's and V2 Procede unable to control boost accurately without v3 harness so you may overboost...

Please explain what you mean.
So you're saying that Shiv adjusted the settings to come up with this map?
Then where is it?

Upgrade to V3. It is an important upgrade with much better boost control and a boost safety routine.

I had the V2 torque settings to 75% and still overboosting to 16+ psi.

V3 is the remedy

Perhaps you can taper boost by reducing the torque at the higher rpm's.

I really don't think Vishnu will ever fix the V2 Product and make it work as promised.

I understand what the user can do to their current V2 map to make it a so called "DP" map, but that's not the OP's question.
The question is "Is there a map for downpipes on V2?"

There is not a DP map out there for V2--period!

True...I guess that is what V3 is for. Sure hope they fix the overboost problem with a new V2 Map and a Datalog fix would be good too.

I think the boost target issue is based on the control method. The fix is V3 because it requires new hardware and software to control the boost in a different manner.

Not the answer you are looking for, but I think that's the issue.

Well if that is true...then it is Vishnu's problem to fix. If you are new to the forum and in case you didn't know. I'm NOT buying V3. V2 is suppose to work and the Pied Piper has no affect on me. Went from V1 to V2 and that was enough.

I don't want to switch between 2 different maps, DP's, CIA, IC. Just want a slightly tuned 335 with no problems.

That mofo needs to fix V2. Where is the V2 Map?

I feel better.

agreed, charging for an upgrade that never worked properly at best and is downright dangerous at worst is bad juju, charging even more for the fix is pretty outrageous
