Hey guys,
I recently moved away from the Reno area but thought Id still throw up a tech question.
I have an '05 forester xt. Sti : turbo, intercooler, up-pipe, fuel pump, cat-back. Invidia catted downpipe.
I recently moved to Fayetteville NC
elevation about 300 ft.
The tune I have is from Matt at K-speed, I feel like its a pretty good tune but I got it dynoed here just to see what kind of numbers I was making.
in case its hard to see: it says 226 whp/ 238 wtq/ AFRs hang out around 10.5/ boost peaks at 18.3lbs
I was expecting closer to 250-260 whp...
I was looking for issues that might be hindering my power.
My thoughts:
-I am running a tune for 91 gas
-I am tuned for a way different elevation
-Would an intake help that much? I thought subaru stock intakes werent too restrictive till bigger power numbers
-Tuner recommended a EBC to keep boost up later in the rev range
-Cat back cant be that restrictive...??
from unabomber: "Which exhaust diameter is best? Exhausts have 3 diameters:
1. 2.5": Good for 300-350 HP
2. 3.0": Good for 500-600 HP
3. 3.5": Good for 600HP + "
Thanks in advance guys!
