What other mods would benefit this set-up?

Roush Supercharger
SE Racing 9lb. pulley
Pro M maf
K&N air filter
NKG TR-6 spark plugs
FRPP 9mm spark plug wires
Walbro 255lph fuel pump
FRPP 3.73 gears
Magnaflow x-pipe w/cats
Magnaflow cat-back exhaust system

Would a fuel pressure regulator and timing adjuster be worth it?

I'm basically building the same combination you have on my '98.

I just picked up a set of P&P SVO Heads to go on with the S/C. My next decision will be cams. Haven't decided between PI's and Comp. I like the idea of the PI's for the lower cost and the emissions testing, but I really hate to see these heads not used to their full potential. Did I see LT's on your list? If not that would be one of the first things I'd consider.

If you are running the stock SVO EEC, you may be able to benefit from a Timing Adjuster. I just installed one on a freinds NA 2000 GT and there was a noticeable gain.

If you have a custom tune and your tuner did his job, you probably won't get much from it. A few things that aren't on your list that may help . . .

Headers
70mm TB
PI cams
colder T stat?

Also, where is your MAF and filter? I relocated mine to the fenderwell shortly after I got my SVO installed and it ran a bit cooler according to the gauge.

I also had my blower ported by magum powers. Maybe more of a pain for you since your blower is installed, but I think it helped.

With my open filter sucking hot air from the engine bay on a 94° day, I dyno'd 280 rwhp on a MUSTANG dyno, with a RICH tune (A/F <10.8:1 from 3400rpm up). I asked for a rich tune to keep temperatures and detonation under control on a road course.

I'm going to install a 70mm TB and have it re-tuned now, I think my CAI is making it run even richer than my dyno sheet says. I'm hoping for 290rwhp on his Mustang Dyno.
