can't drive wot? i recently did full exhaust, pacesetter lt, tsp catted y, borla cat back. Now when I drive my 02 ss m6 runs fine from start to half throttle but if i attempt wot it laggs and has almost no power>? what do you think this could be and how to fix it/
Dont quote me on this, but I had a similar problem on a different car and it turned out to be the MAF. Ran fine when I would ease on the pedal and all but if I punched it, the engine would bog and RPMs climbed VERY slowly. A guy told me he had the same symptons in his GT and it was his MAF. I replaced mine and the car ran perfect. Might be worth checking into.

I disconnected the wiring to the maf but nothing changed still lacking all power past half throttle. Do i completely take off the maf for a mile or two? I also took it out and cleaned it with electronics cleaner and still no change. Would o2 sims for the back two 02 sensors help or is that not even close to the problem? Thread Starter

i replaced the maf lid put a sb in for looks bought o2 sims for the back two and still nothing has changed. Now i have decent pull from low rpms but bog from 4-6k then full power at the top. Still cant go full throttle from idle to 6k but from then on its fine? Any clues?
Just an idea don't know if it will help, have you ever replaced your front O2 sensors. I know that the actual sensor part is very sensitive. It may have been damaged during LT install, or you just may need a new maf?

I would first check for a hairline crack in a spark plug, then the rest of the ignition system and the fuel system.
brad8266 may be right. My car for two weeks has ran like **** normal dirve but does fine wot. Now that I changed my O2 it is running better in normal driving conditions but still bucks 
. My was due for an O2 change though since I just hit 80,000 miles and you can tell a difference!!

my car only has 26k on it so i don't think im due for an o2 change. ShouldI just get plugs and wires changed now since I planned on upgraded them when I get my h/c packaged?
If the car ran fine before the LT's and exhaust then something changed/happened during the install. It is highly unlikely that a part just went 'bad' during this install. I agree with brad8266. Check your plugs and wires. Maybe a plug is cracked or a couple wires are not seated all the way.
Probably a good time to change the plugs and upgrade the wires. My advice on the wires is make sure that you hear and feel the 'click' when putting the plug wires on. I was obsessive when I put my MSD's on. I insisted on hearing and feeling the click. Let us know what you find.
