TT Boost settings on Hefner GT1000TT setup?

[Infantryman]

Apologies in advance if this has been asked and answered--I simply couldn't find where.

As I understand it, the Heffner GT1000TT setup runs about 850hp (crank) on 93 octane pump gas at one boost setting, then the boost can be dialed up to create approx. 1000hp on 103 octane (race?) gas.

Does anyone happen to know how many pounds of boost are being run at each of those two settings? I own one of these beasts, often get that question, and am ashamed to say I have no freakin' idea what the answer is?

Answers that correct any misconceptions I'm operating under, real or imagined, are all welcome.

Usually around 18 psi on pump gas and 23-24 psi on race gas.

You can set the Heffner TT up a # of different ways. My Heffner TT has a dash mounted TurboSmart gauge/boost control with 4 settings. I have 3 different tunes as well. My settings are 19lbs (91 octane), 21lbs (93 octane), 23lbs (C16), and 25lbs (also C16).
