Will my car be fine? more inside...

I would not do it. I would wait to install anything that deals with fuel/air and computer until you get there. It would run like crap for the duration of the ride. Most CAI do not take long to install.
Or buy your own tuner and tune it yourself. The gas money u spend and cost of the tune would equal a top of the line tuner....with tunes. Good luck!!!!

I would imagine you could install everything you listed except for the CAI before you got to a dealer. blackonblack06 is right about buying a handheld tuner, but I wouldn't use that to replace the real thing. I know guys that have tuned their cars for a couple of years and then have gone to a good tuner and they were able to free up a lot more horsepower. I installed my SLP loudmouths, and Bassani xpipes w/ highflow cats before I had my car tuned. I actually drove around with no problem on this combo for about a month and a half before getting a tune. Then I installed the CAI when I got to the tuner before he tuned the car.

If you install the SLP off-road X-pipe, (NO cats) You'll either need O2 sims or an SCT tuner + tune with the rear o2 sensors turned off.
Other wise you'll get a CEL and go into limp mode.
Same for JLT CAI.
Modular Warehouse sould be able to sell you and ship you an SCT 2 with the JLT tunes and the O2 sensors off.
The Zex tune is for the dyno.

I personally like SCT much better than Diablo.
Support after the sale is where its at.

Take a look at their forums.

I have yet to see a car go into limp mode due to a 02 CEL

i ran my car for a month ebfore i bothered removing the rear 02 from the tune.

just did not have time to get it back on the dyno and the car never went into limp mode just showed a CEL..
