I've recently changed my setup completely with the exception of the injectors and cams.

Now the car idles fine at 14.7ish but when cruising it seems to bounce around from mid 12s all the way down to high 10s. the only reason i have boost leak checked it yet is bc i need to make a new one for 4inch inlet, which ill be doing today or tomorrow.
I do not have a tuning cable at this time and need to get one.

possible issue?
front 02 sensor?
boost leak?
or that it was tuning with boost leaks and now that i don't have any its running rich?
exhaust leak?
bad wideband sensor?

looking for some input, thanks guys

 

Are you on speed density?

An exhaust leak would show the car as being lean.

Possible that the front o2 is on its way out, mine began to go rich but threw a code immediately.

 

No still on maf, i take it for tune and SD soon tho.

I did a vented catch can along with put a tial bov (non recirc)
Can i test the 02 sensor without having evo scan?

 

It did throw a code btw I'm going to find out what it is today. Prolly from it running so rich

 

I would find out what code you're throwing and tune the car now that you've changed your setup.
