@Terry@BMS I need your help bud (or anyone else) Not sure why but i couldn't send you a PM for whatever reason.

Anyway, I think i may have just walked into a shit storm. Or at least it feels that way...

A few guys on here helped me get rid of a P0050 code i was getting last week after first installing the JB4. Huge thanks to any of you if you're reading this. I uninstalled the unit and yanked the plugs for other reasons. regardless, I ran the car for a little while, no codes. I swapped the denso plugs with HKS plugs that i had planned to install. Plugged the unit back in and still had no code. I'm assuming it was a connection issue...

Flash forward to today, i just picked my car up from the shop. I had them install a wagner intercooler w charge pipe/air ducts and ultimate performance hfc downpipe/midpipe combo. He said he heard the turbo's spooling and he's a buddy of mine so i believe him. However as soon as i drove off the lot, nothing. No reaction from the turbos. Took me a minute to realize why the car felt like it lost 150HP but soon enough realized the Turbos aren't pushing any PSI (at all). Nothing. I also now have two engine codes P0420 and P0430. Apparently something with the cats. However i did not think they would cause any codes to pop up because they came with high flow cats.

I logged my drive home in map 2. see attached. I didn't do a 0-60, not sure if i have too. I just logged what distance i had to get up to a decent speed. Honestly it feels like my motor just shit the bed so i didn't want to get on it at all.

High flow cats and a catback exhaust can cause over boost, especially with a jb4. However I think the EWG wires (or something like that) will help you out. Best to email terry directly

Yeah I’ve been seeing a lot about overboost and the EWG wires are
