Ok cool I didn't think there was much difference I just wanna figure out what my next upgrade was going to buy. Currently I have 16% pulley CAI cooler plugs---> I was thinking about either upgrading injectors, Methanol/water injection or exhaust,

A mini is never going to be a big HP car...unless you spend a TON of money on the motor. Look at sway bars, better brakes, better tires, lowering springs...stuff like that.

if you have the CAI and the pulley already the exhaust will be the next restrictive thing. (catback atleast). the header can flow pretty well until you get a cam. but the stock cat can flow 400hp.
with injectors you need a tune. a un tuned 380cc injector will actually run richer under WOT and give you less HP. and the mini wont run with 440's or 550's without a tune.
injectors are only needed when you start messing with the topend of the motor. aka big valve head/portpolish/cam

good advice
Right now im not super concerned with great handling since I'm basically just spend most my time on the highway. This is the reason why I wanted to just add a few more horsepower without putting too much into it as far as money; I know it will never have the hp that a v8 can achieve. Up until last year I used to have 1970 ford maverick with a 302 sbf motor putting out 350 hp rw but the mini is a blast to drive when comparing it to other similar cars. Getting back on track basically right now I plan on only doing one upgrade at this time so I wanna make sure I do the most beneficial upgrade for hp gain.

the r53 will RUN with bigger injectors but it wont be happy and will be at like a 9:1 AFR on 550cc with a 17% pulley.
you need a tune. i had mine in my car for a week before going to helix and getting jan to tune it while he was there. since then i have seen a mpg improvement even when compared to a bone stock r53.

I would insert a custom tune at number 2 or at worst 3 in your list, Salty. If you're doing a cam, you really should tune it.

Also getting a tune For my car was of course something that I had considered but Im not sure What options are available for my area (I live near Baltimore). Sorry for all the questions you have probably heard before but I need to get all my facts together before Pulling the trigger on any modifications, So far I have been extremely lucky with spending probably only spent 300 or so on the few modes that I do have and want to keep that way.

as for tuning, you have mynes and rmw, they are the only that can do remote tuning. waymotorworks I think you have to send them your ECU and they can flash it. that's pretty much it for tunes.
no need for a tune with a catback, but if you have a header back, the tune can be slightly changed. also with meth, you can choose to be dependent on it or not. if not tuned you never have to worry about it. if you are tuned for meth, youll always need it

Not sure I would call a cam one of the top three bangs for the buck. Sure...if it's a track car, but not for a street car.

Are there any aftermarket cams out there that are good for a daily driver street car? Every time I hear about someone swapping cams....sure they have a little more HP once you get the engine wrapped out and the rpm's are over 4000+ rpms.....but anything under that, most dyno graphs show that the motor actually looses low RPM HP and TQ.....what you need for a fun daily driver. What good is a daily driver car if you don't have any power down low.

You'll probably get the most enjoyment out of something like a rear sway bar than the other things you are considering. Having said that, I love having a sportier sounding exhaust. I'd buy an exhaust for its sound alone over the couple extra horsepower you might get from a cam or injectors and tune. Sure, an exhaust is a pretty poor investment if all you are after is power, but what do you enjoy more? 0.1 or 0.2 seconds off your 0-60, or having a car that sounds bad ***?

the NS1 and RMW street cam have more of a focus on midrange than topend. shouldn't sacrifice low end. theres also an adjustable cam gear from thumper so you can orientate is as such.
I agree that you don't want a super aggressive cam, unless you track, but I always play in the midrange, 3400-5000 where peak torque is
