Paul, are you sure you have one? It depends on when you bought it from what Scott Hart says at IPD. Here is what I e-mailed him:
>Soctt, I'm looking to find out more about the ECU upgrade for my car. >
>Info requested:
>HP & Torque curves. (I've seen these on line.) >what torque limit is in 1st gear/all other gears >what speed limiter is set at
>what rev limiter is set at
>other mods required to reach quoted hp value (I.e. Exhaust) >other mods offered (and expected gains)
>Cost for "other" mods
>which components are changed in chip >timing advance etc.
>what is max boost presure in psi or bar >how long is max boost allowed?
>is boost pressure or torque reduced just before shifts? If so by how >much?
>what differece is kept between econ and sport mode shifting? >will Winter mode still start off in 3rd gear?
>recomemded fuel octane
Here was his response:
The stock 1st gear torque limit is retained in our automatic applications as well as the stock torque reductions at shift points. Early programs had no speed limiter, since November of '97 we have been using a program with a 155 mph speed limiter. Rev limiter has always been 6400 rpm vs the factories 6200. No other mods required. We do not promote any other upgrades as we feel that the integrity of the drivetrain will be sacrificed at increased levels of output. No parts are changed in the ECU, Mass Air Flow information is modified in the programs. Max boost is 14.7 psi. / 1 BAR. Max boost is allowed indefinitely as long as a good supply of 92 Octane is available. The stock knock sensing system is unchanged so any detonation caused by extended high boost runs would be squelched. Winter mode and sport econ settings and functionality are unchanged form the original factory settings.
Some of what you're asking is detailed in the links below from our website.

Please let me know if I can answer any other questions.

So Paul it really depends on when you bought your ECU. It sounds like the boost presure is higher from what Scott is quoting though.
