ST20V - Vaccum signal

[Futo_gt86]

CAR - KE70 Wagon
MOTOR - ST20V
USE - Project
PROBLEM - ECU tuned in TPS
OCCURS/STARTED WHEN - I get this this running

So, I recently learned that my Razorback ECU ran a stock 20V that had open quads with trumpets.
Pretty much the same set up I have.
I was just going to run this motor off this tune. Yeah, nah
I found out it was tuned in TPS only by the owner and I very much doubt the use of fuel air ratio used in tune.
The ECU has MAP but not used.
I figure it best to have this thing tuned in MAP and TPS
Whats the best way to pick up a map signal on open quads?
I read in a old tread to use vacuum lines from 1 & 4 T pieced?
Now I'm still a bit of a noob to 4age's and don't know of anyone who can tune in Brisbane.
Who would you guys suggest?

just tune it off TPS v RPM and it'll be fine. the only gains running a MAP sensor will give you is fine tuning at very small throttle openings (less than 10%). for most people it's not worth the hassle of making a vacuum tank (feed off all 4 inlet runners post throttle), and hooking up & tuning with the MAP sensor.

i know plenty of motors running TPS v RPM tunes, with no MAP sensors, and they haven't got any drivability issues.
