Your line pressure is a little higher than stock which is predictable with the Transgo kit. To get more pressure you'll need a regulator spring with a higher value

Yes, but that spring is designed for a specific pressure range...pretty much what the OP has.

line pressure,(518 46rh) i have a direct gauge on my car to check LP, it had 70psi in 1-2-3 gears at idle. i manually activated the kick down lever, it had 110 at idle, i have a 3800lbs car with over 700pound feet of torque. i want to ad LP. when i backed the adjuster screw out 2 full turns the gauge starts to flutter 70-90 1-2-3 and 110-120 with KD activated, all at idle. what can i do to add psi but stop the fluttering.… trans-go kit in VB also, no psi in p-r -n at idle What engine speed did you experience the flutter ? Record that speed, the raise the engine speed higher with the lever back and report back - still fluttering? Less/more?

The pump is capable of putting out over 300 psi at idle so it's not a lack of pump capacity. The regulator is the key.
Some full-race VB's regulators are set up to over 200 psi line pressure, not sure how it's done.

Yes, stock pump. The pump is capable of much higher pressure than the regulator allows.
