Upgrades, looking for estimated HP gains

[sportmanst]

Currently (as I type this) installing an MRBP 4" straighted TB SS exhaust, what is that going to add for me in regards to RWHP?

Also in doing upgrade research into turbos and injectors and fuel systems different packages/setups are rated for different hp ranges.

What is your estimate of HP gain on these mods:
Above mentioned MRBP exhaust:
Zoodad with replacement higher flowing Air Filter:
Tuner: I know this one - - up to 120hp
Upgrad to 155cc injectors:
Upgrade fuel lines (thinking Stage I from ID):

As far as the turbo, it depends on the gains from the above mods. With the hp gains you estimate, what range of Turbo would you suggest?


Thanks for all this help guys/gals.

Since its not a 7.3, I'd leave the stock intake alone and preserve that new turbo you're talking about.
