Some Questions about chips and injectors

[Rantheman]

Alright so you guys see my mods below so could a run a TW chip with positions Stock, High Idle, Economy, Daily, Tow, And Either Street Or Extreme I really don't want to upgrade my injectors if i don't have to. I don't want to blow smoke this rig I use for towing and long trips and. second was is the rough hp for street Vs Extreme

The chip will still make a huge difference with stock injectors. Street and extreme will both max out the stock injectors but extreme feels alot more peppy. Extreme also smokes alot more than street.
