Has anyone else experienced this issue. While driving under normal conditions up to 0 vac that car seems fine. However while in drive and the car sees positive pressure the wideband will dance all over the place and the car will just bog leaving me unable to accelrate. This primarily happens in 3rd, 4th gear. When the car gets placed into I or L under same conditions, the car will at that point begin to handle the boost a little bit better, up to 5 or 6 lbs as per the boost gauge from the manifold. Any advice on this would be much appreciated. Mods are:

• E67
• Auto
• s256ET
• 2.5 BAR Map
• E85
• 80lb Injectors
• Stock Fuel Pump
• 2.4 Throttle body
• HP Tuned

 

Mine is a 2009 2.2 hptuned as well. But supercharged not turbo And i used to have that issue with my trifecta tune and when i created my base tune on hpt when i entered boost going over 40 in 4th or 3rd. What i did was have the car enter PE earlier and seemed to fix the issue. Try lowering the tps required to enter pe

 

Set the TPS enable low like 15-20% and set PE MAP enable around 98. This will ensure you hit PE everytime the boost comes on regardless of engine speed or TPS.

 

​​​​​​​this is exactly what i did

 

It works for me but my car is manual, never tuned an eco with an auto
