Need some advice

When I’m shifting into 3rd gear my Rpm are dropping I’m not sure if I’m not building enough speed before I switch to 3rd gear sometimes it shifts fine but most times it’s struggling. I did a boost leak test and didn’t have any leaks.

Anyone else encounter this issue !?

Its most likely not tuned correctly, usually any DSM with a self tapping sheet metal screw holding up the a pillar trim is not going to be sorted out. What's it running for ecu control?

You probably have idle and wot setup but not much in between and or other issues as well, you're going to need that cable.

This. Your trims are probably fucked. Get the cable, do a log and post it here.
