North start throttle body

[LHRxXD3adXx]

Any one know where i can get the tables for this throttle body i use hp tuners. Ive put in a few but my car runs lean with them.
There is no vacuum leaks or anything else that would cause a lean. Thanks

Probably need to know what maf you are running to get you the right table.
