Problem after new CAT today
My 94' 855 has had a code for inefficient cat for a while now. After putting on a hi flow cat today, when under boost(maybe 9-10 psi) I feel a little hesitation in acceleration and any more throttle/boost(11-14 just before fuel cut) and the engine "really begins to misfire". I'm thinking my old cat was somewhat clogged and now there is more air then fuel. Forgot to mention I upgraded to a 16T turbo. So shouldn't the ECU compensate for the higher air flow and dump more fuel?
Any input would be highly appreciated.... CJ
Should mention the code is gone and there are no new ones.

Whats up Tech!
Yes, I did a stage 0 and then some since getting the car last Nov.
Just got back from driving around about 30 miles. Seems to be doing a little better but still busting up under high boost.

ah, forgot the number but they are the same autolites used in the turbo mustangs. Actually seen them used in a few different boosted cars.
Put them in months ago though. Car ran great until it came off the rack at the muffler shop today. At first I was thinking something got shorted by the welding but it probably would not even start if that was the case.

It might be the plugs. The Autolites usually don't do all that well in the Volvo's.
I am running Bosch Platinums but people have had problems with them as well.
Does the check engine light flash when it acts up?
I have a problem with mine kind of like that as well but only sometimes.
