Will 1000RPM make a big difference?

[TYTILIDIE]

My motor is fully built and when I had the 700r4 I was running about 56-5800RPM. With the 80e, I am using the stock ECM and it seems I cant get over 4600RPM right now. Not sure if this is related to my 1600 stall converter but I know that before I do what I have to change the ecm to shift or let me rev that high I want to make sure it will be worth it.

Thoughts?

yes its worth it, if your motor can spin that high.

Fixed a truck for T-Bone last friday, someone installed 80e and had shift points at 4200 rpm, Sucked donkey balls.

Sure. Power = torque*rpm, so if your turbo provides some torque up high you'll be lacking some serious HP numbers.

^^ what he said. Look to see where the engine is making its power, and adjust shift points accordingly. Otherwise, you are shooting in the dark.
