High gear Low RPM jerking under low throttle. MAFT just installed.

[Majikterror]

I had a car driving perfectly fine. Then I installed a blow thru with MAFT. The only problem is they sold me a 3.5" instead of a 3.0" MAS. I have the car at the starting point of tuning. I have to jumpers set properly and the S-AFC set properly and Zeroed out. With the idle turned 2 turns. I can't drive the car normal it has to always be in low gear with high rpms or it feels like weight transfer on an AWD car while it bucks at low rpms at high gear. Is this normal because if it is, that is a big suck. There are no boost leaks. It just likes high rpms. My car spools like mad quick and the EGTs don't go in the red and are at 950-1000 F during idle. I don't have a logger just an S-AFC and EGT for now the cable for my pocketlogger grew legs apparently. Any help please I need this car for a DD.

Do you have a wide band you need to look at your afr's when its doin the bucking thing it might be gettin to much fuel thats what mine was doin before it was tuned.

Where did you splice for the RPM signal for the MAFT. I had the same problem for a month and the ECU just didnt like where the white wire of MAFT was spliced. My power transistor was shutting down at low RPMs. Just disconnect the white wire from whereever you have had it hooked up. If you use the MAFT just to translate and the SAFC for fine tuning then wont be having problems not having the wite wire hooked up

I have a 94 eagle talon 2.0 non turbo. It is doing the same thing wen I'm in a higher
Gear it wants to kinda bog or die a lil bit but wen in lower gears at higher rpm it don't do it all.
