pualscrossfire.com says that between the Needswings Dual CAI and the 74mm throttle-body that comes with it, there is a gain of 20 RWHP dyno proven. Right now my goal is 300 crank HP, so it likely ads around 25 HP. That's fanominal. $800 is a lot for a CAI, but when you consider the cost of the 74mm TB and V8 MAF housing that come with the kit not to mention the fact that its a very large, polished and high quality dual, plus its a massive gain for a CAI. Its a pretty good package, I think I want it. Black filters, high gloss black tubes, yep. The only reserve I have now is that I wonder if he puts things on sale for holidays. With my luck, I'll buy it for $800, and the next day it will be on sale for $649.

Here's what I think I know about upgrades and what I would like to do.
Stock________________$---- - 215hp
ECU Tune_____________$340 - 21hp Needswings, TVT, or Upsolute
Needswings Dual CAI___ $800 - 20hp Needswings
Under-pulley kit________$360 - 12hp Vivid racing, are there others?
Exhaust______________$560 - 12hp? Needswings, TVT, or Borla
Fuel pump and injectors__$60 - 5 to 10hp? Needswings
Plugs and Plug Wires_____$215 - 5 to 10hp? Needswings
Upgrades_____________$2,335 - 75 to 85hp
New hp____________________295 to 305hp

Can anybody help me find any errors or anything else that I can add? And are all of the stats on these sites RWHP? If so, can I re-add the 20% powerloss to the wheels to calculat crank HP since my current goal is 300 crank HP. And what do the Teflon coated valve covers do? Can any power be expected. Lastly, the TVT exhaust is a dual 2.75 inch and even borla is only a single 2.5 inch pipe. How much more power, if any, does the TVT exhaust have over Borla or Needswings magnaflow? And are the SRT6 exhaust manifolds bigger than the N/A? With the other mods, how much help if any will this give me?
