Thanks so far guys, I am soon to purchase the Zeitronix Wideband O2 and EGT option, I have been reading my ass of and am somewhat understanding where I need to be, my questions are as follows:
I want to run 15psi with the mods I have listed in my sig, what would my target AFR be? I am thinking going for 11.3:1? That's just my guess from what I think I understand. 91 octane is as high as it goes here, also my egt's should only be around 1400 correct? Also, I have no ignition control, it's all stock. I've got 440 injectors and the SFMU, so, anything I might be overlooking or any advice, I would greatly appreciate. Thanks thus far though, since 2 years ago, I have learned how to build my own car and now turbo it, by just reading on this site and nowhere else. I am my own mechanic now because of this site, so, bring me to the next level of boosting. TIA.

as far as I can see the only way you'd be able to "TUNE" anything is just by raising and lowering your fuel pressures.

Ignition control is where it's at dood. Even though you have a wideband it's not like you can tell your ecu that you want your target WOT A/F at 11.3.

megasquirt is tuning. an SFMU is not....really ....tuning. even though thats how my car is setup.

Not next year though

yeah with all that money spent on your parts list I would def go megaquirt or similar setup. its a shame you can probably find TONS of power with a complete tune. pulling/adding fuel/timing here and there.

First off thanks for the help and advice. I really want to go megasaquirt, but I am really really in the dark when it comes to using it, I have a laptop and the know how to hook it up, but as far as tuning, I might as well go ride my bike and save myself the trouble. I've been on MSEFI.com and read a lot, but still just don't get it, I am more of a hands on kinda person and would learn way faster that way. Am I missing some really good articles on how megasquirt works? I just don't know. Anyone have an idea on what I should do at this point? My motor is pretty much built to the balls with almost every bolt on, I would love to use megasquirt, is there like a simulator or something you can use? Any way, thanks let me know if you got anything else for me.

I do have SS lines for my fuel system except for the feed to the rail, but the line back to the fuel pump from the SFMU is SS bradied, and from the test port on the rail. I just am so damn lost when it comes to fuel maps, VE tables and whatnot. Just need to learn a lot more. Thanks for the input fellas. More......

Gotcha. The way I read your original post, I thought you meant that all he did was tune it to get those gains. That would be a bit ridiculous .

I forgot to add... Mustang dynos have a reputation for not being very accurate with their numbers. The reason is because they don't use a large enough counterweight to accurately measure power. They work great for seeing how much extra power you got of a new mod though. I'd be willing to bet that your friend is closer to the 250-260 range if he really is running 12 psi.

as touched on above and in an effort to help educate since the topic is about tuning: Mustang dynos are basically good for determining improvements in direct relation to one another, and not necesarily showing the actual horsepower for that vehicle whether turbo or not. The reason I say this is because the "numbers" can be easily manipulated if the predetrmined profile for that vehicle is not used. (this profile takes into consideration wind resistance, weight, and other specs pertaining to each car individually)
If you look back at the posted dyno, the vehicle make information etc is hidden. Not to say that this was the case... but as an example, if the car was an Integra and they used the profile for a Civic, the numbers will be skewed for the better more than likely.

Just passing that on as a tidbit, but when you do plan to turn up the boost above 15psi... and you will... a megasquirt and dynojet would be the better option.

SFMU is tunable, with the proper ring/disc/spring + bleed valve. But it is not consistant, uses high fuel pressures to force more fuel and needs to be adjusted frequently. Not nearly as efficient as electronic tuning, but it is tunable.
