Custom tuning question/Automatic trans

[Ggradtech]

Does anyone have any insight? I have a custom tune installed. I'd rather not mention the vendor, as I'm hoping they will help me out and fix it. When in "D", 1st -2nd is perfect. 2nd-3rd happens at maybe 1800 rpms or so. 3rd-4th about the same. 4th-5th happens with no real increase in RPMs and almost feels like the car "bogs" a bit. Under more aggresive throttle, it doesnt seem to be an issue. Wanted to ask if it an easy tuning fix, or if it turns into a more complex type thing. Thanks!!

under normal driving? mine does the exact same under normal driving and it doesnt bother me. I figured it was for fuel economy. Under WOT is where mine shines....Its perfect for my style of driving/racing.

Depending on device. The SCT has an option to change the shifting parameters of the transmission by percentage. When my car just had a SCT canned tune you could change how it shifted. Most Auto transmission tunes have the car upshift itself very quickly to get gas mileage and to have the converter lockup as soon as possible. If you have a stock converter then it might not be needed. Its pretty common for the auto cars to shift quickly like that under normal driving.
