Would you say this is low on torq ?
Just been on the dyno and got 348.3bhp / 310.4lbft
The spec is
Blob wrx
vf35
walbro 255
Induction kit
full decat
550cc injectors
sti tmic
and a few other little bits ect,
This is the wifes car so number chasing is not that important but 310.4lbft seems low to me,.
Any thoughts

I just had my bug sti mapped, it's nearly standard apart from cat back 3" exhaust and panel filter,RCM fuel pump and mine made 310lbs.
Have you decatted it? Are they standard headers?

Torque: how much? Or how much when?
I have a similar set of mods on my Bugeye WRX wagon.
Fitting a set of ‘Harvey Smith’ wrapped and ported headers and a matched uppipe from Alyn at AS Performance (along with a small map tweak) improved torque by over 50% between 2,000 and 4,000 rpm – just where you need it on a daily driver.
Max torque of 324lbs/ft improved only by 5% but, critically, arrives earlier at 3,800 rpm instead of 4,600 rpm.
Fuel consumption improved by about 6% as you can mostly do what you need to without having to drop a gear or rev the nuts off the engine.
All of that equals better drivability, improved performance and lower running costs so, in my opinion, makes it one of the best mods on the car.

My torque is peaking at 3.8k already without the Harvey kit, Do you think the Harvey kit is the reason for the extra torque ? Might be an avenue worth going down should we want a tad more,.

headers and up-pipe will make a difference
my blob wrx with vf35 and rcm headers makes 354bhp and 365ftlbs non avcs
similar car with same mods apartf from exhaust/headers/up-pipe made 340ftlbs and 333 bhp
both on rcm dyno and both mapped by duncan
get it on a different dyno for a power run mate 1st

.......... Torque lbs/ft
Revs ...Before ...After ...Gain
2,500 .. 125 ......170 .... 36%
3,000 .. 140 ......228 .... 62%
3,500 .. 180 ......308 .... 71%
4,000 .. 270 ..... 322 .... 19%
The ‘before’ and ‘after’ figures were from different rolling roads/mappers so obviously there’ll be some variance, but you’ll get my drift. And I’m still on a 2.5” exhaust with a sport cat in the downpipe.
Congrats on those healthy looking power figures, btw!
