jrsc tuning

When I go to have my dyno tune done with my jrsc I need to upgrade my injectors to 30#, right? Do I really need a new maf?

You need to go to 42`s and yes you need a new MAF to match

There is a BIG Diff between the ZX3 and the SVT , you need 42LB injectors and yes you can use the MAFia if you want and keep the stock MAF but a new MAF will make better power , you could allways just go to a larger MAF housing keep the stock MAF electronics and use the MAFia with it

You need to contact your tuner and see what he wants to use , Some tuners dont do things the same

How much diff in power between the MAFia and a 70mm maf. The MAFia is a bit cheaper and I know that it will fit on my stock intake. But will the 70mm maf fit with my stock intake and the pipe that jr sent with the supercharger kit
