Most likley 225 still or 230 at most. Don't go by what the box says. COI's give 0 HP, and same with OD pulleys. Exhaust maybe a little and the delete kit 0. These really aren't upgrades. Your most noticeable upgrades are heads, blower, cam. These were the reasons I went with a carb.

I agree with Killer, if anything your just going to have a little more throttle response, it will rev up a little faster.

My car when it was 100% factory when 14.9 in the 1/4, then I did pretty much the same parts as you and I went 14.8, but who knows that could have just been a fluke and I could have just shifted at better rpms or something....

Like the others stated you didn't get any big gains. The bigger TB will give alittle throttle responce but doesn't do anything else, you can only push so much air through the stock intake/heads. You will need supporting mods like the others stated to net gains from the TB. probally freed up a few ponies with headers/exhaust the stock stuff sucks. CAI like my mac are for looks mainly, it's been proven that the stock air box/ minus the silencer and a K&N drop in is the best bang for the buck.

loosing the a/c dropped you a little weight nothing else, an electric fan and 3g alt would gain you something. Try some 92+ octane and throw some timing at it like 12-14 for starters, another free hp gain. Another good mod is gears like 3.73 or 4.10's..does nothing for hp but drops your e.t. and pulls nice on the street. The new upper intake will net you a small gain also but help with throttle responce big time but you are fighting the huge stock E7 plug, a basically stock 5.0. wont gain much from a chip or even a tune. I don't like off the shelf chip or thier generic tune a dyno might help to clean up air/fuel on a stock motor but you only get like roughly 10-12hp..save your money until really tear into it.

listen. get a set of 373 gears . those are good mods but w/o gears, youll feel like something is missing. remember, all these mods have to work together. also advance your timing.

You will have to get a good cam and head combo with that intake to see the power gains you are looking for
