S4 T2 loss of power
Alright, so I'm at a loss of what may be the issue. It started after I parked it for about an hour and a half. But my power is down alot. takes alot to get the car going from a stop, almost stalls out. boost is working normal. starts spooling soon as I press the throtle hits full boost fast. but still feels sluggish in boost. compression sounds normal (from ear test 3 good whooshes front and rear). replaced plugs and I'm getting spark. Wideband is reading rich but not overly rich. 12.4 or so in boost. 13/14s while cruising. fuel pressure is good. Car fires up soon as you turn the key.
Feels like the car is under tons of load. even slowish to nutral rev. is barley idling.
Mods are
3"DP to stock hollowed out cat
Apex'i N1 3" catback
3"TID
720CC secoundarys
Rtek 1.7
FD fuel pump
Sard RRFPR

Other info is backfires almost everytime I shift or let off the gas. and the electrodes of the plugs I replaced where worn down to a point. I think my timing may be out of whack, but I haven't touched it since I've owned the car. this is new.

I would do a real compression test. Does it take longer to reach full boost, and does it still make the same pressure it did before? You can build boost with 1 rotor, but it just takes longer to get there and you'll have much less power than you did before.

Problem sort of fixed itself. Not shure whats up. It was actually spooling much faster than normal.... just felt like it was bogging out, or under hevy load. like it felt like 1500 rpm's in 5th gear, at 4000 2nd gear full boost (10 PSI).
I have an apex'i N1 as far as exhaust.
I'd really like to figure out what happend though. because for it to all of a sudden just go away is strange. so I'm thinking electrical.
Maybe CAS?
