O.K. This might help. I've got an older V6 (2001) and have access to alot more tables than that. Although I haven't seen an HPT file for your car I feel comfortable going out on a limb and saying it most likely does as well. The tables I have access to which are relevant to this topic include:
-Max Torque Timing (They warn you not to mess with this one)
-Max Allowable MPH for each gear Timing Limiter
-Max Torque Output allowed at RPM values in each gear
-Max Torque allowed in each gear
-Max Torque allowed at various RMP values
-How much spark reduces how much torque
-Max torque allowed by the Traction Control Freak System
-Commanded Air Fuel Ratio and Commanded Spark if TCFS kicks in
-How (or if at all) injectors disable during TCS
-Speed tables and RPM tables Commanded AFR and Commanded Spark tables, and injector disable tables for declaring both Gear Abuse & Differential Abuse
-Seperate tables under Transmission for declaring/activating/recognizing and effect of Abuse Mode and Torque reduction
With HPT I can set the Max Torque Output to 640 so I think you wouldn't need to worry about exceeding those figures!
P.S. there is a gentlemen on this forum codenamed "Frost" who I believe sells a dual PCM with a switch setup. You could use HPT to individually licence each one and have your own personally customized tunes on them. And please feel free to post in a little more depth, your (sadly negative) experience with other tuning companies or products in the lounge, as it may help others make decisions as well. Or at least make me that much happier that I went with HPT anyway!
