Looking to get a tune (going with nelson) but was wondering if i should get 42 lb fuel injecters before the tune. right now i have my maf senor right on the tb with the cone air filter and a flowmaster cat back with electric fans. But add an under crank pully and porting the tb or just going to get a 80mm. But looking to do a turbo or sc at tax time (long time i know but no money)
