Default Question after full exhaust install

I noticed a very slight miss at idle and there is definitely a miss at 3k plus when I get on it. Is this a computer issue that would be fixed with the dyno tune? Or did I not seat a damn plug wire incorrectly? I triple checked the wires but I guess its possible I could of goofed one. Other than that, the car sounds sweet!

Had the same problem, cracked a plug. You also may have damaged a wire.

IMO an exhaust by itself should not result in a miss or require a dyno tune. When I did mine the car ran as before installation only faster.

That's what I though as well. I must have a bad seated wire or maybe a cracked plug. I checked all the TR55 plugs, gapped at .55 and torqued to the specs on the box. Brand new MSD wires.

Double check the routing of the O2 sensors. Check the instructions as many guys have got this crossed up on thier install and had misses.

Oh yea, those puppies are good. I spent probably 45 min. routing the wires. Driver's side to driver's side, etc. I also ended up unclipping the plug to get a little more length so I could run them back behind the fire shield like stock. I then zip tied all the wires away from the headers. Those starter wires were a beotch to get to but all is away from the LTs.

It was a plug wire. I took each one off and put them back and it cured the problem. Will be on dyno tomorrow at 3:00!
