So what computer system is this? A Gen4 setup? Post up your tune, both modded one and the stock one.

A few things:

1: Copy the High Octane table to the HO (DOD) and LO (DOD) just to be safe.

2: Under Engine, Torque Management, General, you need to disable "Tip-In Limiting, ETC limit". It's set to Enabled. If you can't see this, then you need the latest beta.

3: I'd also zero out "Torque Reduction, Pattern Z" under Trans, Torque Management, as well as zero out "Torque Reduction, Downshift".

4: Last, go to Engine, Fuel Control, Power Enrichment, and set the Power Enrichment Delay RPM to 0, Enable RPM to 0, and RPM Hyst. to 0. I'd also set the MAP setting back to the factory of 55 (you have it at 85). This will bypass the "PE Delay Timer", which HPT doesn't give you access to, and go right into PE when you meet the "PE Enable TPS" settings.

5: If you don't have any cats, you need to zero out ALL the "Cat Lightoff" tables.
