alright guys not sure if you know the deal but someone stole my SAFC, boost controller, boost guage, air intake. I was planning on putting the car back to stock but i have a couple questions.. Since i have a 255 fuel pump and an AFPR will i have to put a stock fuel pump in it or can i just turn down the pressure? what would i turn it down to? Now my other question is... just to get around the tuning part would there be anyway i could keep my evo 3 16g turbo and just use stock injectors? Could i just get a new boost controller and change my injectors back to stock and pretty much be done with it? if i can't keep that turbo and i put the stock turbo back on, stock intake manifold, stock exhaust manifold can i at least keep the intercooler and pipe on? I'm trying to get around so i don't have to spend any money. I don't have the money to replace all that was stolen adn then get it tuned by someone. I either want it back to stock, or back in form where i don't have to tune it. Thanks guys
 
Check your manual for the correct stock fuel pressure.
Put back in your 450's.
Leave the boost as whatever your turbo is gated for.
Just don't beat on it until you get the parts again.
 
Stock fuel pressure is 43.5psi, the 255 will flow a bit more, won't throw off a stock tune really too much.
If I were you, if you have an eprom ECU, I'd get a keydriver chip for 90bucks(which is a lot cheaper then 2-300bucks for an SAFC) and will give you a decent tune for the 550's.
I'd also think about getting an alarm, any alarm even ebay, get a 2way pager alarm if you want. And a battery backup siren thats a good 130db.
You could also go ebay style and get a boost controller for 10bucks and a gauge for 25..
 
well i have 650cc injectors.. how will the chip do with 650s? i'll buy the MBC thats like 40 bucks on this site thats not a problem.. I just didn't want to spend another 300 for the SAFC and all the other stuff plus 175 an hour to tune it 2 hours away from me.. I don't have the money for that, but i do have the money for a 40 dollar MBC and maybe that chip if it would give me a decent tune.. how much boost would it be safe to run with the chip with 650's if that will work and where can i get one? i'm not sure if i have an EPROM ecu bbut i heard all the 95's had them, If not i'm sure i can get one. I just don't want to deal with getting it tuned, i'll go completely stock before i have to go through with the SAFC plus a tune.
 
Alright man you're a life saver. I almost didn't ask these questions and now i'm glad i did. Now i'm getting pumped to have my car back this spring.. not in stock form either :)

edit: oops also not sure if i asked this or not but could i still run 21psi of boost? also how would i be able to tell how much boost i'm running once i get the car set back up?
 
Buy a boost gauge, it'll tell you how much boost your running. Like i said I got a 25 dollar boost gauge, and It's as accurate as any autometer(has been put up to test multiple times) and again it's a very simple device. You could use your stock one for now if you want, it should be accurate within a couple psi's. But I wouldnt push it past its 15psi mark..
You can probably run 21psi and stay at a good A/F ratio, with the chip. I assume you have a logger since you had an SAFC? So you'll be able to safely see how high you can run.
 
No i don't have a datalogger.. but i'll get one before i start running the car in spring, I don't know how to use one, but when the time comes i'll just post the log here and get some help from you guys.
