Hey guys! First post on here, super excited to be a part of the community/website.
Okay, so recently i have come across my FIRST problem with my 1997 Talon TSI AWD 5-speed. I was looking/searching, and could not find an exact answer to my question. So let me explain what is going on. I bought the car BONE STOCK. Car only has 64k miles on it, and i am the 2nd owner. Ran/Drove perfectly UNTIL I recently had a full 3" turbo back exhaust installed.
Now a little back story. I have been driving the car on weekends, and nice weekdays that i get off. The upgrades i have done to the car are as follows.. Injen Intake, Greddy upper/lower hard pipe kit with fresh STM silicone couplers, Greddy type-s BOV (Recirculated) AND THATS IT. When the car had just those mods on it drove beautifully! didn't skip a beat at all.
I had swapped out the spark plugs to fresh NGK BPR6ES's gapped to 0.28 because it still had the OEM plugs in! I have not yet put on a new set of NGK 8100 plug wires.
The only code the car threw before exhaust was a P0141. (Rear O2 sensor) Like i said regardless the car drove fine. NOW i had a 3" Megan racing downpipe, and an HKS catback exhaust installed on the car. Nothing else has been touched, i have had the car in the air multiple times, checking everything underneath near the wastegate, all vac lines etc. I have looked everything over, and everything is the same way its always been.
Now when i take the car out, it runs/drives normal but the second i try to get into boost 50%-100% throttle the car falls on its face and stutters like crazy, creates zero boost, and feels like a nasty fuel cut, or boost cut. This car is still on the stock T25, and stock tune/boost, none of those lines have been changed.
I do not plan on modding the car further, I just wanted a nice intake, hard pipes, and a nice clean exhaust. Does anybody have any ideas on what could cause this?
I did read up people saying throwing a 3" DP on the stock T25 can cause "boost creep" due to the restricted factory O2 housing, but either way i feel i would still be able to get into boost? Any thoughts/ideas would be amazing, it's pretty frustrating, and would like to figure this out. Thanks guys!
