Wideband problems Please help
Ok so i have a lc-1 with the db gauge. i pretty much 100% sure its wired and grounded properly cause i ran it on my car before i put my kit on in the same exact location as my turbo down pipe, and it read perfectly fine. But here comes the problem when i put my turbo kit on and instal the sensor in my down pipe it reads 21.9 dead lean. So i moved it up closer to the turbo and then the reading got better, 16.5 ish to like 18.6 ish. Idk what is going on with it. I am running dsm 450's that i just got back from injector rehab and they all tested 100% fine. Which btw when i put the injectors in and started the car before i put the turbo on it ran really rich at idle 12.0. I'm waiting on a new base map to come in and we'll see how it works when it gets here.
So has anyone had this issue? or have any suggestions as to what the problem may be? Any help is greatly appriciated. thanks in advance.

Re: Wideband problems Please help
the only suggestion i might have is that as gas cools it contracts so the farther away from turbo it gets, not as much is reaching the wideband pickup... have you brought it to a tuner yet or are you tuning it yourself? moving it closer to the turbo (if it seems to alleviate the issue) might be one of your only solutions

Re: Wideband problems Please help
the sensor should be a minmum of 18 inches from the turbo, you could have a exhaust leak from turbo to downpipe which can give false readings
