Yeah, You know, these AFCs are totally useless. I only gained 25 rwhp. What is 25 rwhp to an N/A engine. Blah, nothing!

PS. I didn't know what the ECU was doing but I do know what AFC does. It's hard to belive that WRX gained only 3 hp. Now, how do they know? Did they do it on a dyno? An AWD dyno? It's somewhat suspiscious. My buddy with a N/A Supra gained 29 rwhp with intake and exchaust.

You gained 25 rwhp on your SC300 eh? I heard that story about the guy getting 29 hp on his Supra on the MKIV forums. It's the same engine... maybe that engine really needs the tuning... Do you have a copy of your dyno chart you can scan?
The guys at Import Tuner used a Dynapack AWD dyno that's supposed to be very accurate for the WRX. If the SAFC yields some big gain with my V8 I'll be sure to put up the dyno chart so people know what to look forward to. I'm guessing that if that's the case the WRX is already pretty tuned up.

I don't have a copy of the peak runs. All I have is the copies of the dyno when he was adjusting the dyno. You won't see a big improvement there, while it does show it a little too. The curve is little smoother and HP and TQ curves are about the same. When I go to the dyno place again to install my tranny supercooler I will do a dyno again and scan it to show you guys. Hehehe.
