Hi from newbie. just bought s trim mustang, mine has 38lb injectors? Do I need 42lb? Will I need new tune if I buy CX racing intercooler. Dyno sheet says 350 HP?

Yes you need a new tune for a IC,

42lbers are better but 38 will be fine for lower boost

and depending on what size pulley you are running 350hp sounds right for a non IC'd car.

note, on guys saying you cant run 10psi with a 3.33 and fmic that what i hit at 6k rpm, of course i dont have the fuel so the rpm has been limited and not i make 9 at 5900 if i want to bounce off the rev limiter lol. also my fmic is treadstone not cx racing, and home made power pipe, but still 3.33 pullie and v-1 si trim
