Bad hesitation on acceleration from a stop.

[mb10190]

87 Grand National Running 93 octane

Hello, need help with this issue I am having after installing all new mods...
Mods are

5.7 TT chip 60# injectors set for 18# boost
MAF Translator LT1 MAF
GN1 72MM throttle body, Plenum and spacer
HPT 6262 Turbo with 45mm external waste gate with 14# spring with manual boost controller.
And supporting fuel system fuel pump and lines
3" down pipe and full exhaust.

I have set fuel pressure, TP sensor and all the dip switches in the Translator per instructions that came with the TT Chip.
I'm at a loss as to why it hesitates when I am pulling away from a stop. (Runs great after that)
If it were a carburetor I would replace the accelerator pump... LOL

So, any help with this would be greatly appreciated.
Thank You
MB

Check your connection between the MAF and the translator. As I recall, the pink wires need to line up but you can plug it in backwards and it will run. I wish it was only one way but it isn't.

Also, did you install a high stall torque converter at the same time? Not likely the stock converter will allow that turbo to spool up and make power down low.
