On a bone stock car, if you added those mods the increase in hp would be:
K&N: 3 - 5
C&L w/ 75 TB: 14 hp
3.73: -3 hp
Tri-Ax Shifter: 0 hp
UPD's: 8 hp
Intake Spacer: Waste of time...not needed with the plenum
X-Pipe: 10 - 15hp
A stock GT 5 speed has 225 hp, so these mods would give you about 40 hp tops for a total of about 260 rwhp. However, in reality expect about 245 - 250 hp.
Your value of 248 hp is simply not possible on your car w/o those mods unless you have added heads or cams or something significant.
If you look at my mods which are all of the above PLUS a high flow catback, CAI, and an SCT tune - I am lucky if I have 265 rwhp.
You will loose rwhp with gears, but don't loose any sleep over it. It is really an effect of how the dyno works with a gear ratio in 4th that is no longer 1:1. It is really not a hp loss, but rather a limitation of a dyno.
