New chip burn after cat install? - ZR-1 Net Registry Forums

Dmod81 · 08-04-2012

I just had cats installed yesterday. Let me tell you, it's awesome not smelling like exhaust anymore.

Took the car on a 270 mile road trip, and it felt really down on power a couple of times. Once, it wouldn't rev past 4500. Felt like the power key was off. When I would push in the clutch on mountain switchbacks, the rpms would drop and kill the engine. Happened twice, scary stuff on a mountainside. When I got it restarted, I could again rev through the full range.

So my question is, do I need a new chip burned after installing cats? Also seems like these issues may be unrelated, as I was at 9000-10000 feet at times.

Car is 1992, SW headers, cats, B&B gen1 exhaust, haibeck chip for all mods but cats.

Thoughts?
