ok i have a 1995 talon and i have been running lean the only mods i have is bov and intercooler and a boost controller but i am not boosting it i am running 10psi i know i am running lean cause i pulled my plugs and i have a way bad exhaust leak at my flex pipe and can smell it i changed my fuel filter and there was way sick stuff in it i was wondering could my fuel pump be going out or what else could cause it to run lean thatnks

Although spark plugs can be a good sign that you are running lean, a logger would be ALOT better to diagnose the problem. If you dont have a logger I would turn down the boost a little until you can log it.

Also, I didnt notice an after market boost gauge, are you reading from the stock gauge? If so you should get a new one ASAP.
