the injectors will only flow so much fuel.
the tunes you get when you buy a TS chip or whatever are basic tunes(from that particular tuner that is, all tuners are different, but most will equal out in the power/TQ department. Im not talking edge, or bully dog or banks here either.) for the specific vehicle and some light mods. No matter what anyone says. UNLESS you call up or talk to the tuner and say you want more power down low, or you added injectors and turbo and you need more fuel, timing, ect....
On a 140 HP tune, youre only gonna see about 80 HP. same goes for the 100 tune. the injectors simply dont have enough flow to support the volume of fuel desired.
Some people get performance injectors when they have injector problems, say after 150k miles or more. My Philosophy is why replace with stock, when aftermarket/performance stuff is basically same price, and gets you more power, or economy out of your truck.
You can de tune larger injectors(to a point) to run with a stock charger. that way, you can up the fuel amount once you get more air flowing. alot of people do that.
