Not sure what you’re trying to achieve....but generally speaking a GOOD tune alone is capable of adding min 60-70 up to 100 more HP/TQ @ the crank, (I am running gearhead/ORA personally & really like it) that adjust both the ECM AND (more importantly basically) the TCM- earlier/stage 1 cobb tunes didn’t touch the TCM + if you live in hot climate and/or will be pushing it hard on a consistent basis then an upgraded HD intercooler in stock location or even larger FMIC may be good idea to help maintain that peak performance more consistently, not really “add” any HP. I haven’t noticed an issue since I live in MA rarely do I find the truck heat smoking & losing power that I can notice. There’s no HP to be found in a CAI really, but downpipes and/or turbo adapters probably good for another 20-40hp or something. But really anything above & beyond that you’re probably looking @ upgrading turbos or stroking the engine building bottom end upgrading pistons/cams etc. & all that power above & beyond the first round of bolt-ons always gets pricier & pricier. I suppose nitrous is an option but to me isn’t “real” - however methanol injection on other hand could be worth checking into - dual benefit of allowing engine to make more power add more timing & run cooler.
it’s a 5500 lb 4x4 offroad truck on 35”s....But I’ll be damned if there’s anything close to the total package once you have a solid tune & running those downpipes & adapters w/ a decent intercooler (personally I’d go stock location like CVF, whipple, Wagner, mishimoto etc) you’re talking bout 460-490whp & 550-580rwtq + running through a 10 speed auto & 4.10 gears w/ ability to run in true “AWD” in dry conditions. I mean just listening to that statement in and of itself & considering what was available in the truck market only 10 years ago it’s really crazy what the Raptor is capable of w/ mild mods.
I don’t really think you need more than that in this truck, as it is w/ those mods you’ll well exceed the capability of both the brakes & suspension if pushing it- so then you’re talking more $$$$ if you actually wanna USE all that power on a regular basis in all conditions safely & repetitively.
