Hope that helps!
From what I understand, it is airflow and torque table #4 that should be modified and the other 3 left alone. You are saying the opposite

The codes are as follows:
P1870 and P0725

They have no idea what it is. My car is hardly drivable

Anyone have any ideas?
DTC P1870: engine torque signal abnormality.
DTC P0725: engine speed signal abnormality.

Call up BR, and ask them to get you a map with adjusted Torque and Air Maps...

Well I'm going somewhat by looking at the changes the EcuTek tune did to my car compared to stock. The #4 tables were untouched although that doesn't mean it's the only way to do it.

Leave table #4 alone .. you can change the torque limit tables without changing any thing else ..
Plus Gunzo said leave them alone! haha

Yeah if you are making more part throttle boost from a MBC in a GSR or MR it will also help you avoid limp modes.

If Gunzo said to leave #4 alone, then why do his maps have #4 changed and #1 through #3 stock. Check the maps he posted in the EvoXforum. What you are saying is not reflected in his maps.

It could be there is more than one way to skin a cat then, perhaps Gunzo or others can chime in on what all these limits tables specifically come into play?

Nope .. those values are off the MRs .. there's no point changing these maps .. doesn't do anything AFAIK for now

Your primary concern is map #2 and #3 .. I can only trigger #1 under certain conditions which I'm still trying to figure out ..

I downloaded the GSR map that you posted and it has #4 airflow/torque changed. 1 through 3 are unchanged.

So what are you saying NOW? Are you saying that the changes in #4 in the GSR map mean nothing? Why did you change the numbers in #4 in the GSR map if they mean nothing?

Yeah, I started tripping the p1235 once I put on the ETS 4" FMIC. I used to trip the 1241 before, however I adjusted the Airflow & Torque Limits, not it seems I need to adjust the limits again more.

I only get the p1235 in 5th gear on the highway, boost spikes to about 26 psi. I am tuned for 25psi. Grr...

So map limits 2 & 3 are the most important ones it seems or who ever said on this thread. Do maps 2 & 3 can look the same?
