Reading here in the forum, I learned that the Waste Gate actuator is very soft, so I thought in block the air flow to it. Is when I installed an industrial Festo’s air flow controller. The results were impressive. The boost stay fixed, I could completely block the air to the N75 valve and the turbo still loose boost at hi rpm’s, keeping it safe, proving it is a soft WG actuator.
Can anyone comment on if the wastegate actuator problem / limitation would be fixed by replacing the diverter valve with an aftermarket unit (Forge / APR)?

Not sure of the relationship here here.
Waste gate and diverter valve are two different things. The diverter operates off throttle the N75 is what controls the waste gate for on boost aplications.

Thanks Joe, I'm thinking the N75J valve is probably a good investment.
Is the Festo pressure regulator or something similar worth while for stock Turbo? Can anyone tell me what I'm looking for exactly? I've been poking around the Festo website, lots of products, not sure exactly what specs would suit. They do have a branch in Vic, but I really don't know if its worth my time with my basic mods...
Finally the bars arrived.
I installed the rear one today, next week I’m going to the front one.
I need to fabricate spacers because the U-bolts are over sized, the threads were not long enough to do a good tight.
Yeah Whiteline have done this a few times before and sent the wrong bolts with the sway bar. Send them an email mate and the should send you the correct ones!

BTW how is the new Garrett turbo coming along
I'm developing a new actuator for the WG, something softer. I'm not going to use the N75 to control the turbo.
In the next week I will start the manufacture of the exhaust manifold.
Plautos, I'd be interested to get your feedback on how you find having done just the rear and than adding the front. Was the front an obvious improvement, having done the rear, or to keep it balanced, etc.
I do understand how and why they work, just curious for your reasoning for doing both.

Just with the rear bar I felt difference in the handling. The rear becomes sloppier when doing slaloms.
With the front in place I felt the car smother, however more in the ground. In the rain the car in not sliding how it uses to slide.
I’m feeling the car more precise.
Both setups are on the hardest mode.
