performance chip questions

[youpey]

I am interested in possibly putting in an apten performance chip for my 2001 5.0 explorer. I have a couple of questions before i call.
1. Is this the best chip made for the explorer
2. How difficult is it to install for someone with a little more than basic knowledge of cars
3. Is this an impressive performance upgrade or just a barely noticable one.
4. will this affect the reliability of the car
I have the mac cold air intake on my car and I have ordered the pro m mass air flow sensor. I will probobly be getting a flowmaster exhaust, but not just yet

thanks

1. From what I have researched, Yes its about the best.
2. Its very easy to install and comes with good directions.
3. I noticed pretty good gains with mine. Most opinions here are the same on it, good. Especially with an electronically controlled tranny.
4. Just get the chip programmed to the other upgrades your gonna do.

Also theres alot of opinions and info on this if you search for it.
