Did you ever get the tune perimeters figured out to hold boost?

Any updates on the fix for the throttle closure and holding boost?

Found the owner and car was tuned by Jon Lund. It was tuned with SCT tuner, anyhow I will post some logs.
I will post some logs. Does it look like the car is setup for e85? I am not having any running issues, just want to make certain tune looks good before I start running it hard. I will get some...
I am not certain. I bought car from dealer who didn't know much detail about the car.
Good morning,
Just wanted to have some experienced tuners to look over my tune file. I recently purchased this car and no tuner came with the car. I have my hptuner mpv2 and downloaded the...
Yes, I made some adjustments and the LTFT are running 0 to +3 in cruise areas. I am going to add 1% to see how it goes. Trying to get the LTFT to 0.

Jason,
What tuning changes do you think I should start with? I know tuning the maf 5%, 10%, 12%, 15%, to do this requires highlighting area or all of maf and multiply by 1.05 for 5%, 1.10 for 10%...
Jason,
My running fuel pressure at idle on the Fore fuel regulator holds steady @ 55 psi. The regulator is vacuum referenced for boost and am not certain what my driving pressure is under boost. I...
Where do you see DFCO enabled? I thought it was disabled. I was having trouble with my fuel trims. They were running LTFT -18 and STFT -10 running pig rich with the CAI installed. I will put it...
Well, I removed the CAI and reinstalled my stock air cleaner. I worked on the tune and have average +3 LTFT and +6 to -4.5 STFT. I updated my maf and got it into a better range and worked on the...
I appreciate your insights and help. I made some adjustments to my tune and logged the car. The LTFT are better as well as STFT. I have a wide band coming and will work on it more to get it more...
5FDP I appreciate your insights. I will check the burst knock. The tune prior to CAI install my fuel trims ran -5 to +5. The fuel trims are way off and it goes pig rich. So where would you...
2009 CTSV installed a CAI and now my LTFT at cruise are running -15 and STFT are -5 to +5. When I accelerate slowly the trims go down and slowly creep back up. If I go full throttle the car go...
I have been working on my tune and recently installed a CAI. The tune is attached along with a log file. The issue is the under hard acceleration it feels as though the car is lean or torque...
I would check your timing table. I have same cam in auto and my tunes are posted on this forum. My car idles fine and at startup idle is 950 and slowly comes down to 750 per tune as it warms up at...
Here is another couple log files. Along with tune. I am still getting a lean condition and need to get me an AFR gauge. Got one ordered so I will just stay out of boost or park the car until I can...
Thank you for letting me know about my VE. I did work on some tuning and logs. Guys take a look and see what you think.
Thanks I will work on it.
So adding 20% to maf is essentially adding fuel or air?
Can you give me some insight on how to add 20% to maf. I would appreciate some instructions or help to make certain it is done correctly.

Well, did some checking under the hood and found the aircleaner tube disconnected from the throttle body and one vacum line disconnected from the tube. I am going to drive car today and see how she...
Thanks
I appreciate the help and I do have a fuel gauge and will work on the trims. I will research and work on the tune. It is driveable but needs to be tuned prior to doing more spirited driving. I...
