Back in the saddle as they say.  LOL  Snow go away.

Got to run some newer tune files on Monday before the snow.  With very little timing (zero knock) car felt faster.  What are you cooking there Unleashed? 

Stay Tuned my friends...  :)
 
I want that too! But I need to figure out the P0172 and P0175 I am having now and then when it's cold outside.

But with all the snow we have here, I can't get WOT logging done for Torrie...

Hope you get the P codes sorted out.  I see your running the big 3bar map.  How is it running on 94 octane?  Do you have meth injection or no?

here is info on what code mean.
P0172/P0175 Diagnostic Theory for Shops and Technicians
When a vehicle has the fault code P0172 and or P0175, it means that computer can no longer automatically adjust the mixture between air and fuel. Code P0172 applies to Bank 1 and P0175 applies to Bank 2. Code P0175 mainly applies to V6 or V8 engines because 4-cylinder engines generally have only one bank, though there are a few exceptions. Some of the high performance 4-cylinder and straight 6-cylinder engines (such as those in BMW and Lexus) split the cylinders into groups of two or three and call them separate banks.

When the code says that the Fuel System is "too rich," it means that the computer has been subtracting more and more fuel, which is called Long Term Fuel Trim. Ideally, the Long Term Fuel Trim should be close to 1 to 2 percent. When a code P0172 is set, it means that the Fuel Trim is anywhere from -15 percent to as low as -30 percent compensated. When this happens, the computer knows that there is an improper condition in the control of the Fuel System.

The first step in the diagnosis of a code P0172 and/or P0175 is to look at a minimum of three ranges of the Long Term Fuel Trim numbers on a scanner. Check the idle reading—3000 RPM unloaded and 3000 RPM with at least 50 percent load. Then check the freeze frame information for the code to see which range(s) failed and what the operating conditions were.

Crash: not sure how to do this. Do you know which parameters should I check with torque pro?

Short and long term fuel trim banks 1 and 2.

STFT and LTFT is the gauge abbreviation
 
Oh! I solve the P0172 and P0175 codes issue. Fuel trim and idle strategy relearn and everything is fine again.
 
Thanks for the update. I am in the middle of generating a new file generation for his controller currently and will roll it out further once more research and finalization is complete.

Tune is loaded. Poor winter tires, they are screaming in pain searching for grip, in vain.
