had my s/c on for about 2 weeks
I got my s/c on about 2 weeks ago and i love it, i just have a few questions on whats next and what i need next.
1.When i turn off the car i smell fuel in the drivers footwell, i have looked under the car and in the engine bay and see no leaking fuel. anyone have an idea about this?
2. When im in boost and i lift off the throttle i go very lean on my UEGO, im wondering where this pressure is going without a BOV and if anything bad is happening?
3. I plan on getting a few additions to my car soon and im basically planning on getting just a boost guage and modifrys mod to make the temp gauge work again, i dont want a bunch of gauges but if an oil pressure/temp is needed i will get it. I will also get a krank vent for insurance because the stock pcv valve might be letting boost in the crank. i havent heard any need for a fuel pressure gauge but some guys have them, to keep my S running safe and strong will a boost gauge,wideband and modifrys temp modification be sufficient?
any other ideas would be great. thanks/

Usually fuel leaks take place at the fuel rail. A dry piece of colored paper placed under the fuel rail will show the leak. Check all fuel fittings. There have been many reports of damaged injector O-rings causing leaks.

under more examination it smells like very rich burned fuel, i looked at all the fittings and there is no residue or fuel there, i do have a test pipe and recently changed the exhaust back to stock, im going to get under the car today and see if there might be an exhaust leak, where the TP connects to the exhaust.

the AEM renders the fuel reclamation system unusable (fuel return something like that ). The smell is the gas from the vapor return system collecting in the pan.
i THINK the competech uses a bypass system which if i understand it correctly, refeeds the boosted air back into the intake side of the compressor. If it goes lean for a short time, when you come out of boost, its ok, ie.. you release it goes lean for 2 or 3 seconds... then stablizes around 14. You should be ok.
Of course, you should ask your tuner if this is all ok, this is whats been explained to me.
Good luck to ya!
