Default low power after opti install

well after taking the car apart for the 2nd time bc the damn opti got splined wrong and then my crank bolt threads got jacked up i finally got the car back together with the help of a few buddies. however, on the first test drive (cold) the car studdered under a load (more than 1/2 throttle) then when it got warm the car runs smooth but has low low low power levels. the opti was installed right im 100% sure and the firing order is right. im getting everything i need fuel, spark ect. the plugs are brand new and looked good when i pulled one after the test drives. anyone have any ideas? thanks

Not sure with a volt meter, but with a scanner that does live readings you can see if it changes counts while driving. Or take it out and try to push it in, pull it out.

I wouldn't recommend trying to push or pull on it. You could mess up the gears.
