Default Load Limit (Max) Secondary

Does anybody know how to correctly implement the primary and secondary load limit adjustment specific to the 08+ STI's ? I cant raise the "Load Limit (Max) Secondary" above 4. Cobb states that the limit can be raised higher by adjusting the "Load Limit (Max) Secondary Compensation (Barometric)" and "Load Limit (Max) Secondary Compensation (Intake Temp)" tables. According to their documentation, they say one can modify the load limits like this:

"For later vehicles, which use the "Load Limit (Max) Secondary" table, it is also necessary to modify the "Load Limit (Max) Secondary Compensation (Barometric)" or "...(Intake Temp)" tables. If you change either of these to contain +100% values, it will double the load limit present in the "Load Limit (Max) Secondary" table (ex. 4.0 g/rev = 8.0 g/rev limit, or 16.0 g/rev limit if both are set to 100%)."

I have performed the suggested workaround but I have a few questions.

1. Am I to assume that the "Load Limit (Max) Secondary" table will now represent a multiple of 4 ? E.g. An entered value of 4 actually equals 16, 3 actually equals 12, 2 equals 8....blah bah blah.

2. Can I just use the compensation table values to set the actual multiplier accordingly? E.g. use 50% instead of 100% to create a multiplier effect of 2?

3. Lastly, should I adjust the calculated "Load Limit (Max) Secondary" value such that it matches the "Load Limit (Max) Primary" ? E.g. if I put in 5 for "Load Limit (Max) Primary" should I put in the appropriate calculated value of 1.25 in the "Load Limit (Max) Secondary" table ? This of course assumes I used 100% as the compensation value for the two tables mentioned in the cobb suggestions.

Thanks in advance.

I entered the values as suggested by Cobb and called it good.

I know that doesn't answer your questions, but, unless you're just curious I don't think it really matters. Just follow the instructions and call it good.

Thanks. This makes me a little more comfortable. I'll experiment and try to answer my specific questions. Apparently, others don't have this issue. I was expecting a lot of replies to this thread.

it doesn't matter what the load limit is, as long as you aren't hitting it. You have a boost limit which is the only concern for you car

My apologies. I suppose I should have stated that I am maxing out the load on my engine. I max out at 4 g/rev before I am even at full boost. Max boost for me is about 26PSI and I reach 4 g/rev by about 21PSI. Thanks for your response.
