yo guys i also just installed a SAFC II in my car the other day..me and my tuner was bored so we decide to install one..didnt take long either. run great now and better gas milage. stock tune was going reallly RICH. but now just need a turbo kit or some bolt ons..imma post some pictures of it once i get a camera.

 

How did you tune it?

 

street tune off the SAFC

 

How did you monitor air/fuel ratios?

 

Wow another reminder, I bought an SAFC-II sometime last year and never installed it on my car. What performance mods, if any, do you have on the car? About how much of a hp increase do you think you got from installing it?

 

i duno how much HP but drives alot better than stock

 

you monitor everything off the super afc controller.

 

performance and mpg increase even without mods (assuming from your sig)??

 

yup..not much bbut its there.

 

I had mine dyno tuned on 2/2/08 with just a Borla rear section exhaust, K&N intake and TM spark plugs...my baseline was at around 252whp and 279 wtq. After the AFC Neo install and tune I got 268.1whp and around 296wtq and that all was done with a crack in my Y-pipe! I am having the new Y-Pipe installed tomorrow @ my friend's shop. So the properly tuned AFC will yield around 16whp and around 17wtq! It's a great add-on mod for $275 assuming you don't have the SRT intake because the piggyback computer will not work with this AFC.

 

Any idea what a stock GS3 pushes at the wheels? I'd like an idea of where I'm starting from.

 

im prolly just gunna order a injen intake since i already have the apex

 

sorry, i meant as in power adding mods.
I know Rock-a-lex made a huge torque gain but I guess it's not an isolated case.

 

You're at around 180whp stock. Since the GS300 stock is rated at 225hp (crank), you multiply that by 80% (because there is an approx. loss of 20% of power from the drivetrain in our cars) and you'll get 180whp.

The GS400/GS430's are around 240whp but some have seen as low as 235whp and some have seen as high as 245whp...stock.

 

I would guess between 170-180 depending on the year because some made 225 and some made 220 to the crank.
