I have a 06 gto with a 402 stroker, cammed, fast intake, nw102 throttlebody. ect....

The car idle fine and drives fine, I have adjusted the VE and MAF, and Idle air flow table b1829, but the car is hard to start, you have to step on the pedal slightly to get it to fire off.

Checking into the b1650, b1651, b1652, b1701

Tried to the math for area of the stock throttle and it doest come close to 4725mmsq, even with taking into account for the throttle blade.

I also noticed when i did a WOT pull the absolute throttle position was at 88.2%, dont knw whats up with that

Idk which way to go, any help would be much appreciated

Thanks Russ

That TPS is correct for full throttle.
Add more cranking airflow

I maxed the cranking airflow table out, no help.
