lean condition on take off, help please

i have been having issue's with my car when i leave a stop light, it will pop in intake and bog then pick-up , i look at my a/f meter and goes to 16. i have tried adding fuel at that point of air flow and has had no change, is there another setting with hp tuner that i can add fuel as i touch the trottle? any help would be apreciated, thanks. 402 with 236-242 cam and fast 102 intake and t/b with 100mm maf.

my wot a/f ratio is aprox 12.5 average accross the full rpm range, only on the initial touche of the accelerator pedal does it go lean.

Set it to full open loop, disable all trims.
Then open the scanner and reset fuel trims

Test to see if it does the same
