I did everything to install my single but when I went to start it ran really rough, smelled like raw fuel, and came out white out of my exaust. I know it's not a coolant leak that is putting out that white smoke, it's the overly rich condition that's bothering me. I tried check all my lines but every thing looks fine. I don't want to finish pulling out my hair so I came to ask for help again!
sorry for the ignorance.
I'm running a power fc and a t-88 single

Did you have the PFC tuned for that turbo? If so By whom? Also state fuel mods. Most aftermarket fuel pumps run rich at idle.

I'd like to be overly rich and white some day. I'm halfway there!

it was tuned by SR for exactly what I have. My fuel mods are supra pump, 1300 seconderies. Stock primaries.

Okay, sorry for my worthless post before, I just thought the thread title was funny.

Do you have an FC-datalogit? This is an outstanding privately-developed product that allows you to access all the settings in the PowerFC for tuning and trading the maps. You can even add a wideband and datalog the A/F ratio with the rest of the data. There is some more info on it in the PowerFC forum:

Have you got any more driving impressions yet? Are the injector sizes set correctly in the PowerFC? Are you sure you don't have big primaries (only the primaries will be running at idle, perhaps the primaries and secondaries are swapped)? Do you know your fuel pressure -- perhaps you forgot to hookup the vacuum line to the FPR, hence the rich idle mixture?

Are you sure it isn't coolant? The sweet smell of burning coolant is unmistakable, so I assume you have ruled that out already.

thanks but I figured it out. The o ring on one of my seconderies did not seat right. I replaced it and it seems to be fine now.
