Fuel issue

Well I think I’m having problems with my fueling. When I get down on it,it will drop lean then go back rich. Sometimes it will just lean out and kinda cut out. I made 1 more quick run to redline and it did like I said. It dropped lean then riched back up before it hit full boost. When it hit full boost a/f went to green, but it was like sputtering and backfired 3 times. My setup consist of a t3 turbo,tubular manifold,tial 38mm wastegate, stock internals, dsm 450cc injectors, obd0, my ecu has a code 13 on it, and I’m using turboedit with a basemap tune by xenocron. I know I need it tuned but there is no tuner around here for like 100 miles. I have been boosting for about 6 months now and it just started doing this tonight. If anyone has any ideas let me know.

I really need some help guys.

You need to get that car tuned. Why are you redlining a motor that hasn’t been properly tuned?

its not a bad thing if its a leaner when ur not in boost but when ur in boost aim for some 11.5 afr’s then lean it out and listen for kocking

get a wideband for 200$ off xenocron and learn urself …im still learning myself just play around with the softwear and read everything u can about it

I know it needs a tune. But it has ran fine up until now. Could it be a bad fpr. My fpr is stock. I dont think its my fuel filter. I can see the filter element on it. Its one of those red and blue filters from autozone. I have a walbro 255hp. Also my dsm injectors are used I guess it could be that on is not opening fully or something. I know its not much to go on but any help will be appreciated.
