What do you really need in order for you to get a tune? i was told you need a boost gauge, walbro fuel pump, and a air/fuel gauge... Is this correct?

What kind of air fuel gauge s everyone using? AEM?

I need a reflash badly i have a turbo back and a intake system and i got 3 defi gauges already.

 

if you go to a tuner that has a dyno you don't really need anything

having a boost gauge is a good idea...if you plan on logging yourself having an afr gauge is necessary

a fuel pump becomes necessary beyond 300 whp

all of this could have been found by searching
