iam going to upgrade my fuel system to a 255 intank 90 maf but what size injectors should i run t he mods i have done now are cai, underdrives,imrc delets, msd, headers, offroad h-pipe,flowmasters, nx 100 shot
Why you upgrading your maf? The stocker can support a ton of hp and a lot more than what your current setup makes. That money can be spent for better parts.
I would definately recommend a Low Fuel pressure safety switch, bottle heater, purge kit and a window switch if you already don't have these. Of course NGK TR6 plugs(or an equivolent plug that is 2 heat ranges cooler) gapped at .035
