13 kit with boost it box

sled worked great except for a low end burble when id come onto the gas from a dead stop. Anyone have any numbers besides the ones that are recommended thta seem to be working good? 5000-7000ft

What year is the sled?

Boost it does not control the bottom end does it?

The Boost-it XIC only starts to operate when it senses boost. That is why I was asking the year of the sled. Maybe has a Polaris fueling problem.

Set your "min rpm" value to about 60, watch sec injector duty% in gauge mode on XIC and ride. I bet you they will start to inject fuel as low as 3500rpm. Correct would be: Threshold only starts to operate when boost exceeds that setting. I guess injectors start to add alot when it reaches threshold?

I had to richen the bottom up and it took care of the stumble

sleds a 13 with 400 miles. 45 miles with boost. never had a stumble before the kit. seems to load up when im coming down a hill to. pretty sure its rich on the bottom. doesnt seem to stumble at the staging area which is about 3500ft.

mine was doing this as well, turned out to be a broken primary spring and not a fueling issue. been breaking primary springs quite often. a lot of people are mistaking this "bog" it is technically turbo lag due to having a broken primary spring causing early clutch engagement before the turbo is spooled
