HP gains by bolt-on mod?
Has anyone found a summary of the range of HP gains by bolt on mod? If so, that would be a great resource for all of us. Even worthy of a Sticky:
1) Stand alone Custom tune with no new parts = ___HP+/-
2) Cold Air Intake with/without tune = ___HP+/-
3) Ported throttle body with/without tune = ___HP+/-
4) Cat-less Headers with/without tune = ___HP+/-
5) Cat-less X pipe with/without tune = ___HP+/-
6) Axle back exhaust with/without tune = ___HP+/-
7) Install items 2) to 6) above, with a custom tune = ___HP+/-
8) Any other combination of mods that go well together (pulley, etc)
9) Octane levels
I know there will be a variation in results, depending on the manufacturer and model of part installed, just curious about the approximate amount of HP gains. Adding the approximate price of these mods would then get us a $/HP.

Great thread and I am interested in seeing other results... Currently I am in process of my own upgrades... dyno time/cost is a factor so at thgis point I an completeing mods and will do two pulls.
2017 Grand Sport M7
First:
ARH Mid-length Headers w/CATS
Borla X-Pipe
Mishimoto 160 degee thermostat
Vararam TCR-7 CAI
Weapon-X Ported Throttle Body
Second:
Tune with all of the above...
- Plan is to complete all mods and do a "bolt-on" base. Then do a turn with everything on and see what we get.
I'll decide at Carlisle if I am going Borla ATAK of Magnaflow Competition axle-back... afdter that i'll probably wait till next spring for next upgrade... Heads/Cam vs S/C... I really want to Road Course track the car... don't want heat issues on track day.

Thanks L1FRDOG. I just bought:
-ARP headers
-Borla Xpipe
-Borla exhaust
-AFE cold air intake
I did this mainly for the sound (except CAI), but it would be great to have an idea what they are doing to the HP.
I am going to do a dyno run stock, with all installed without tune and all installed with tune. I may do a separate run with just the CAI and Xpipe with tune.

I would be interested in seeing this as well. I have ARH mids, Borla X, weaponX ported TB, AFE CAI and a HP tune. I did not have it dyno'ed but I can tell you it's much quicker and sounds amazing. It will break the tires free much quicker than when stock. Plus that sound. They started inside the dealer service area yesterday and about made a lady **** her pants standing behind it.
