I think the squirt size is close. Rich end up the mixture just past what the booster supply....Maybe see what position the squirter cam is in and move that for less duration.......
This is farther down the road test, but will be a simple test.

I always get the main jetting mph correct first and then tune pump cam and nozzles to best 60' times. A good starting point for accelerator pump nozzles for you would be 33 front and rear, orange #2 front/orange #1 rear. If you are launching at 2K rpm for example, use #2 hole up front so you save more pump shot for WOT at launch. With so many different combos it is a long process to get the best setup and I rely on 60' instead butt dyno.
