I’m located in Tucson

I live in AZ and I’m more concern on finding a tune for the tbi and max hp/tq staying emission legal?

Thx for the add, hoping to get a lot of info on my 1987 gmc high Sierra tbi 5.7. Has anyone tried the Edelbrock tbi heads, 3702 cam and intake? Looking to get the most out of my tbi!
