Now to add a dash of reality .. i'm not trying to scare you off... but know the risks.
I have had worse luck than most:
-i have had to replace both turbos. one was me racing it to hard, the other came busted and did not know it until we pulled them off
-i have replaced my boost solenoid spider, extra duty racing killed it as well im sure
-colder plugs fouled my car badly after 10k miles. in my wet climate of oregon i would not recommend going colder plugs. this lead to stuttering, stalling and backfiring at high rpm with no codes.
-just running the 3-bar, aggressive AJP turbo tune i was 2 or more tenths slower than others cars. thats the car lottery, somestimes the same tune will not yield the same results.
-i just Drove for the 1st time at 4000ft elevation. man that was bad. be prepared that if you change elevations DRAMATICALLY the car will perform way differently and not behave as well.
All done i spent 1500$ tuning and in parts, and 4500$ in repairs. it is *possible* that you may not have issues.. or it is equally possible you may see issues. keep this in mind. the extra duty from the tune WILL push marginal parts out the airlock. you should plan on a repair budget to be on the safe side, if this is your DD it would be VERY prudent to have money at the ready just in case.
was it worth it .. for me i will say yes. i did it and have no real regrets. i wish i had that 4500$ back but were racers.. racers break things.
Others have had to replace the transmission, the extra load and the sketchy OEM fluid makes for a bad combo. most dealerships will not replace the fluid so you will need to mod and changer that yourself frequently.
PS::
Also before you go eblow deep, I would recommend only two tuners.
AJP and Livernois. I use AJP solely atm but will try livernoise next year (tax money), I have see to much negative press with others and had my own VERY RISKY tune issue with one of the 1st tuners on the scene and will never go back to him.
Lastly, Ghost call your ford dealership, using someone else's phone as ask for the GM. you need to find out of he/the shop is tuner friendly. My dealership for example will not make any warranty claims if it has been modified. There very anti mod .. some dealerships are more ok with it and ask you to go back to stock and replicate. it is better to know before hand. case in point, they will not change nay fluid that is marked ''lifetime'' so eventually i will destroy my tranny.
