I have the y8 crank pulley(from 1.5slowmatic..thx) to increase the boost on my jrsc and some 440 rc injectors. I'm going to get a tune in a week or 2, should i just take the injectors and crank pulley to them to put on, if so how many shop hours do you think it would take. i'm thinking only 1 or 1.5 hr. or should i put the parts on myself before the tune, the only thing is towing. I also have the hondata s300 there going to tune with on the dyno, so should i do the work myself and pay for towing to the shop for the tune, or pay them to put the crank pulley on and the injectors in before they tune it.
