So I will be getting my car tuned again in the next few weeks and am wondering if my stock 560's will be sufficient enough or if it would just be wise to upgrade to larger for security.
Car is a '06 WRX. Mods: 18G, perrin tmic, inlet hose, spt intake, titek catless d/p, tgv deletes, grimmspeed pnp exhaust manifold w/high-flow cross pipe, greddy evo2, hallman pro rx mbc, cobb ap v.1, walbro 255lph.
Also was wondering if anyone has any experience with pnp'd intake manifolds and if its worth the money. My main goal is to get the car to spool as fast as possible, not necessarily peak hp numbers

 

With the 18G if you secide to go E-85 in the future you will want larger injectors. maybe go 750's they will tune right and should handle all that and e-85
