The HP gains will be diff for everyone dependent on the mods already done for the car. There isn't some magic hp number with a chip. 
Couldn't agree with u more!!
Doesn't Y2K have a 3.0? 10 hp yeah and that was not on a mail order chip.
I say on average 8-9 hp on a 2.5 with an aftermarket tune after all the bolt on upgrades. Headers, maf, y-pipe, cat-back exhaust, air intake. That is tuned while on the dyno, mail order i gues a 5hp gain average.
5-6hp gain for a stock upgrade tune.
Mail order is hit or miss. Has been said a million times before.
No way to know with a mail order. I picked up 20 just playing with open exhaust and air fuel on my NA 3L.
In street trim with just an emanage I was able to make 10HP gain by tuning the A/F. With timing control I could have done even better.
You gotta remember that how well your car does is going to be 50% attention to little details in both the build up and the tune! Hand porting, port matching, valve size calculations, age of the components, grade of fuel, etc.
