yes you are absolutely right, and one of the solutions they arew working on is installing a bigger throttle body, we have a member here already in line for that, but I believe it will cause drivability to be less comfortable specially on low rpms, thats from my experience with pervious cars i owned and modified

They did improve the throttle delay issue, but apparently there's also a restriction on the throttle opening which does modulate boost pressure. He didn't go into full details.
I think this all comes back to that "30% throttle" issue that was mentioned a while back. Toyota must of added this feature to create their torque curve.

They did initially find that issue when tuning another member's (Mason) car. IS200TFOWL is the only member i know with the OV tune, but according to him, he expected more. I wish he could give us some actual dyno results.

in theory it can given that all limits are removed so that boost spike can mimic the same effects of an unrestricted throttle

Oh wow! Do you have the data cable to adjust the settings? If so, perhaps try a lower setting like 2 psi. I have done several datalog runs for Terry with my BMS and down-pipe, and we found out that in some instances we got better results from +5 psi than +6 psi .

How can I get my hands on the data cable and software?

For some reason the data cable is not listed under the Lexus category, but you can get it here.

2nd gear is not a good idea since your test wont be be long enough to produce realistic results
