I imagine their dyno numbers read much lower than most other dynos.

I was wondering this as well, as well as what a stock forester auto puts down(typically)

Mustang Dyno
STG 2 Cobb
AVO High Flow Panel Filter
MadDad 3" TBE

This is a baseline curve prior to 18G/Spearco install. HP so freaking low...I know, TQ is what matters but still.

1st Run 202.8HP / 240.9TQ

2nd Run 204HP / 244TQ

Don't put so much stock into the numbers. There are alot of varibles that can change the numbers slightly. The goal of a dyno run to to make sure everything is running smooth and strong and the A/F ratios looks good.

Your XTs final drive of 4.44 is a big reason why your TQ reads much higher than your HP. It is very common on the XT to have a much higher TQ number.

I have 3 maps on my car and they all dyno that way.
280hp/312tq
293hp/336tq
313hp/356tq

^^^^ Was that a Dave Brown road tune? Think I'm going to him in a few weeks..

fourortwowheels · 11-21-2008, 06:34 PM

yes dave tuned it.

Northwest Tan · 11-21-2008, 06:36 PM

Is that a common issue with the newer Foresters? That dip would annoy me. I don't think my tuner would let my car leave with something like that...

fourortwowheels · 11-21-2008, 06:43 PM

all the new canbus' do it, look at my cobb OTS dyno. im sure it can be tuned out... all i know is you dont feel any loss in power on the street or in real world. just on the dyno and load is applied that nasty curve is what you see.

my tuner says its a common problem he is facing w/ the newer ecu subarus. my 05 sti never had this problem, but both of my fozzys did....

Yeap, see my dyno curves, AP was at 18.2psi, where the tuner's gauge only 16psi.

Got my STI Forester ECU Reflashed at Pulse Racing in Menai, Sydney recently

Mods are..

XFORCE Diff Back Exhaust ( Twin Tip )
GFB Stealth FX BOV
Resonator Removed for CAI

Before Reflash - 152.0 KW ATW
After Reflash - 200.1 KW ATW

Car feels great, certainly has alot more punch then before..

Cheers.
