There is lots of talk about TB balancing and I was wondering what type of balancing gauge would you recommend for TB adjustments.
1) TwinMax?
2) Carb Stick?
3) Home made water column?
The simplest and less expensive would naturally be the home made one .... but would you fill it with water, oil for damping?
Also ....has anyone measured the vacuum value from the TBs? ..... By this I mean "vacuum from the throttle nipple connection with respect to atmosphere".
What I do have is a vacuum indicator where I was able to get the following ...... at idle 17 cm hg of vacuum on both TBs jumping to 19cm hg of vacuum on both TBs.
At 3000 rpm I had 23 cm hg of vacuum on both TBs and they seem balanced at +/- 1cm hg.
(These values are the actual values I measured from my 09 Stelvio)
If so ..... is there an adjustment for this?
The reason I'm asking this is because of the ECU being a MAP ..... this value can determine the air volume at different RPM.
Thanks
