Lt4 tuners please chime in lol
2017 c7z bolt on made 560/630tq
Added kong blower, 103mm tb and 2.3 upper
No matter what fuel 11.8-12.6
No matter 10*-16* advance
Changed plugs
Throttle is not closing and getting all commanded timing
It will not make over 572/685tq
Also note it has dropped almost a full second in 60-130 on a draggy so definitely gained a decent amount of power. But for some reason it will not make a decent pull on the dyno. Any input would be great at this point. Never had this issue with any gen v
Thanks
I can post tune tomorrow but figured I'd post maybe I've missed something
