Looking for some advice...

[asrnj77]

So I am slowly moving towards the new tune...I installed the Wideband, 40lb injectprs, afpr, new vacuum hoses (GP), and walbro pump/hotwire. The fp is set at 42lbs and it was idling great but the wideband numbers are crazy at a steady cruise it swings from 10.2 to 17 and back and forth. It still has the pitbull chip and I'm thinking about bumping up the fp a couple of lbs. I know I need the new tune because of the injectors but I am surprised about how off the wall the wideband numbers are. I haven't taken a dm file after the install because we got some good snow today.
I have a fp gauge but it's under hood so I will need to check the rise from park. Has this happened to anybody before? I plan on trying code59 soon but wonder what's going on...

Re: Looking for some advice...

Is the pitbull chip made to use the 40 lb injectors?

Even the ones that were 40# had generally terrible fueling. There's a reason people didn't stay with those injectors very long.
Furthermore, unless you patched it, the pitbull won't display AFR in the datastream.

Trying to watch the gauge while you're driving is a pointless endeavor. In normal operation AFRs move around so fast you'd never be able to follow it.

Thanks the pitbull is very temporary..I'm waiting on some code59 equipment and the pitbull just happened to be the chip that was in at the time. So far the 40's are idling awesome but need a tune really bad.

I'll probably throw the pitbull on ebay based upon what others have been doing
