The power looks good for the setup. The intake hurts alot and also the exhaust. I really like the Kooks dual 3" setup and switch the midpipes to 3" instead on the knocked down one's. Cleaning both of those up will show big torque gains.

I agree the intake/exhaust exhaust could be a major restriction. On my 402 (Formula) I gained 20whp by switching from an SLP lid and stock MAF to a 104mm FTP lid and Z06 maf. I picked up another ~45whp or so from going from a 3" y and hooker catback to a TSP true dual setup. The intake/exhaust switch took me from 445whp to 511whp/480wtq! My car also tuned by RPM. The tune is NOT your issue, I can assure you that.
I know its not the tune ,I just dont understand with the mods that i have already why i wouldnt get the results that im looking for. when it was just a heads &cam car without the 402 it was making 460 or 470ish then with the 402 went up to high 480's low 490's now with electric water pump,1 7/8 header larger cam i picked up 6rwhp ?
This stuff never ends, heh.

Your airbox/intake tube restriction (not as familiar with the "Goat") and the 2-1/2" exhaust is hurting, but, I think it is something more than the FAST 102 and 1-3/4" headers ... here is my graph. The only difference between the "green" graph and the "blue" graph is the addition of a SDPC 402 short block. This is through a Vengeance ported FAST 90/90 NWTB, CNC'd TFS 215's and 1-3/4" Kooks into a 3" ORY and 3" dual-outlet Flowmaster. You must be pulling in the same or more with your "out of the box" 102.
I believe all of the TFS 225's are cnc'd and the as-cast is the TFS 220 ... someone can correct me here ... so I believe your head flow is fine and more than my TFS 215's.

As cast is the 220 trickflow. Things to consider is how much the trickflow head was milled, what the static compression is, what fuel are you running, what head gaskets were used, was the piston run out of the hole when the short block was put together, what pistons, etc....
ive played with 2.5" catbacks to 3" catbacks on my blown GTO with no noticeable gains. Maybe 2 to 4whp. But that couldve been the day. Hard to say?

Not a firm believer in the svedeOTR intake either, the short runner length and placement of the maf sensor can make a larged cam car are real turd for street manners. With the long intake runner tube of the LPE, powerchamber, etc... the intake place the maf farther upstream from the throttle body alowing a steadier flow of air across the maf. Creating a better running better tuned car.

congrats!
i saw the cam size and i thought it was RPM! Roshan spec'd that cam for me as well but on a 111 lsa for my stock cube 346
btw the dyno does show lower numbers compared to others around
