I've got an ls7 maf with a 100mm lid setup with a 92 mm throttle body, with a ported fast 92. While holding a steady speed, it kind of surges or almost feels like im towing a trailer with too small of a ball. If i unplug the maf and it runs on a semi s.d. tune, it does not do this. Any ideas on how to make this not do this?
