i recently did my build and well got lots of kinks but work them out but the persisten one is the running way rich. I wave the 255hp wally, 450cc turbo inject. and press. regulator plus safc 2. I thought the modern performance 60mm throttle would help but i'm still runnig too rich the car stinks like gas a lot from the exhaust and when i hit the gas it hesitates till it can manage tu burn it up followed by a big cloud of black smoke along with crude gas from the exhaust. i am worried that this my damge my engine any tips I've alredy optimized the air/fuel in the sacf to just 2400 rpm point but I worried to lean it up after that cuz thats when the boost comes in any sugestion are apreciated.

450 turbo injectors... you running the resistor pack? and how do you have your SAFC/regulator set?

...and what's your actual A/F ratio or EGT's?

Well I do have the resitor pack and also missing link my safc is set at -50 in 800 and 1600rpm then on 2400 rpm -25 but even then it's so rich it dosen't burn the fuel fast enough. Also do any of you know if the wally 255hp must be installed with a relay to prevent it from getting damaged?

The fuel pump already uses the stock relay on the firewall, there is no need to add another one.

Thats some outrageous #'s on the AFC. Back when I had one with 440's, my idle was only brought down by -20%.

What kind of pressure regulator is this that you are using by chance? Are you installed correctly??

Also, how long have you been boosted/has this been going on?

what do you have your fuel rail pressure set at? is you O2 working alright?

Do you have any CEL's?

well my press reg. it}s a 1:1 I think it´s the one you get at ebay like really cheap and my fuel rail press is 25 maybe a lil less. I have since fixed a bit the problem with the safc and the smic helped a lot it´s no longer that rich but I still feel slugishness of it before it burns the fuel up it´s less noticeable now but still is there I guess I´ll just have to wait and fix it on the dyno. But I still got to put in the urethane mount cause the stock ones are badly torn the get my exhaust as I want it 2.5 all the way back no muffler no nothing. Perks of knowing the guy that does vehicle inspection! but any way I´ve been trying to get some pics up so all you v¿can see but havent had the time cuz I log on for like 5 min and go but maybe some time this week there will be up. thanxs for all the help any other tips are more than welcome.

Yea, a 1:1 is scary dude.

Also, if your getting a new exhaust, get a 3" back, not 2.5

a 1:1 rising rate? unless you can remap you injectors under boost (never used a SAFC before, dunno if it can take it's own MAP) you're gonna melt your pistons! you're almost better off gettin like 25lb/hr with an 8:1 or so, stock with 12:1 is about right up to ~8 psi, but then you get some pretty high fuel psi (crackin out hoses, been there done that).
