Default bogging issue at full throttle

alright had this issue with my dx and now with my si swap
anything over i want to say over 3/4 throttle the car will fall on its nose its like it just lose power it doesnt shut down it just nose dives and when i pick my foot back up and takes off i was just wondering if anybody else has had this issue before and if there is a cure for it

i have already replaced these parts
si intake manifold (pm6)
si injectors
si ecu (pm6)
si ecu fuel pump

post up any suggestions you might have please its kind of irritating

I used to deal with this problem years ago with any single cam I ran off a pg7 ecu. Check your distributor's base timing...more than likely it's off. Lemme guess...if you accelerate slowly into full throttle it does just fine, but if you stomp it to full it dies.

my guess is you dident switch the tps wires around. swap the tps outer wires around because the tps works bacwards from how it worked on the dx motor. if not that then i have no clue

no i already switched the tps wires i still get a code for the crank angle sensor other than that i dont know its annoying though when you are getting on it and then if your like me which i tend to forget that when you go full throttle it starts to bog and fall on its face i have already changed out the sparkplugs and wires the only thing i have not done to it yet is change out the fuel filter so that is my next step as soon as i can get around to doing it other than that swapped to the si swap i have good injectors and i have also change from the dx to si fuel pump

all i know is its annoying espeacially when you are lined up and you start to go the car still pulls hell of hard but once you reach a certain point it drops and the car starts to jerk a lil cause your in that 3/4 to full throttle range so im open to suggestions
