#134857, "I ran race gas for the first time and now its way rich?"
Hey guys im new on here. I have a JE and eagle build on my 420 with a hahns stage 2 turbo kit and accle 310 injectors and a begi fmu, it fucking rips but i went to the track and put a litte race gas in (1gallon) and holly shit all hell broke lose. It dont want to stay idleing acording to the innovate it is idleing at around 12.2? some times under crusing conditions it will run as rich as 10.8.. wtf is going on then at WOT it is almost identical to the A/F it use to be about 11.8? idk i really could use some help i have sence then put new pump gas in it and still the same thing. So then i ran the fuel psi gague and the fpr is working good. Never had this problem before putting in race gas, and i only ran a 1 gallon to a half tank of pump gas? Did it destroy my o2 sensor. Thanks for the space 2GNT amd sorry if i its in the wrong spot this place is kinda hard to get use to lol. Thanks Colton.

It sounds like you have something else going on here. Did it throw a CEL? It takes a good bit of leaded gas before it ruins an O2 sensor. 1 Gallon wouldn't hurt it at all.

do you feel any performance loss? Just trying to figure out if you have a real problem mechanical wise, or a sensor issue.
Depending on where his 02 sensor is , IE if its not in the right spot, the life/accuracy of those can nose dive.. id assume if your runn 10.8, and no boost, ud se some black smoke out your exhaust..?
you can always trust a dishonest man to be dishonest, honestly, its the honest ones you need to look out for. you never know when they will do something..stupid

Well when it is running at 10.8 it is hard to build boost at all and yea there is some black smoke. I am strating to think that it is the shitty Sidco gas i ran before the track. i dint want to run a full tank at the track, so i was running around a half tank and it was getting low so i needed gas, it was a ran down Sidco how often is premium really use there? Because if it is bad gas then the fuel is gona not want to burn under combustion and tell the ecu to suply more fuel when it really dont need it. It really acts like it is bad gas because some times it runs great just like it use to and then when the gas in the tank gets mixed up it will starts running funky again.. Thanks guys for the help What do you think?

Leaded race gas kills O2 sensors. might want to verify yours is actually working.
