Question 7.5 EFI starting hard

Hi,
I have a 1989 F250 w/ the 460 V8 EFI /C6 and everytime I go to start it ...it starts hard and I smell excess gas (flooded smell) and very rarely it will start easy...also when you get on the petal hard it runs as if it hits up against a rev limiter or is very lean and wont shift untill you back out of it so it revs to the point it shifts ( I have a Trans-Go shift kit in it set on Comp. firm). It is all stock w/ the addition of an K&N airfilter, Accell 8.5 mm wires and Bosch platinum plugs.
Thanks for your time....Wayno
