Here are a few thoughts (I'm not going to address the HP gains...you will find out the results from the tuner when he runs it on the dyno and he will be able to give you different torque/HP options based upon what you are looking to do with the car and its limitations).
From my humble experience, you want to determine your car's best gear ratio/torque configuration for the most likely track you will be running. Ideally you will work with your tuner to identify the torque/HP curve you are desiring. For instance, on the tracks I run on I am often in 3rd gear. I found that 3.73 gears were perfect for the tracks. I have a boosted car (the Super Snake) and used a specific tune from Shelby that they set to give a lot of torque on the low to mid range so using 3rd gear works very well (too much to get into...your tuner knows the concept and will educate you). Shelby set this car up very very well for road track racing.
Now, with that said the SS is not a 1/4 mile drag car. Gearing is too low (hits the rev limiter in 4th before going through the trap) and doesn't make enough torque in the higher RPM range. So, I'm building a car that *I hope* will do well both on the 1/4 mile and on the track and has 3.55 gears. For road track racing, I'm less concerned about HP and more concerned about where the torque curve is. You will be more concerned about torque as well if you are road racing. I have a manual transmission so I don't want to be shifting a lot. Low and mid range torque will be key for the track. Now....for the 1/4 mile I'm concerned about HP pull in the higher RPM range. In order to address that I am adding nitrous
simply to get more HP in a targeted higher gear and higher RPM range. Nitrous is only for the 1/4 mile, never the track.
For the track, too much HP can be a problem (with your adds you aren't ever going to have the issue). Me...I'm going to be about 900HP at the wheels at some point and am concerned that may be too much at the track (low end torque is going to be enormous and I might be creating a long of tire spin so I'm likely going to always have to worry how heavy my right foot is coming out of corners). But, on the 1/4 mile you simply can't have too much HP especially in the higher gears. I'm hoping for a 9 second car so my HP with nitrous in 4th/5th gear at 5500RPM+ will need to be well over 1000.
So...long story short....make the car breath well (which your headers and exhaust and CAI will do), and get the most amount of torque that you can in the speed/gear/rpm range that you most expect to be in during racing. HP does to a degree equal torque...but for you it's going to be all about torque, not HP.
