After the header install on my brothers z i installed tr55 gaped at .050 installed new msd wires. When your drive the car normal its fine. when u floor it from a roll or a dead stop the car hesitates.... im lost gona thro a set of AC delcos in and see what happens?

Don't be so quick to ditch the TR55's. They are an excellent plug! I'm sure your issues are somewhere else. Maybe you cracked a plug, plug wire not on all the way, etc. etc.

My guess is the headers have caused a slightly lean condition and the incorrect AF ratio is the problem,if you cracked the porcelin of one of the plugs you would see a misfire code, a tune would definetly help but in the meantime just give it a couple hundred miles of normal driving to get the LT trims in line and see how she does.

I tried the TR55's and wasn't impressed. Car came with Denso plugs. Went with Denso Irridium. Car runs great.

Looking at your sig I see no headers,or NOS which is why most peeps use the TR's. A lot of us that have both swear by the TR's.

when i switched to the TR55's at first i almost thought i lost power. but still had original wires. so i went with the msd wires and now its great. i noticed bigger dif going to the msd wires over the tr55's

i was skeptical at first, but ill use TR55's or the TR6 later on..over anything else hands down

I think your having problems elsewhere if your having problems with NGK-TR55's. I have them, along with stock plug wires and the car runs great.

it wont hurt to give it another look over, i agree with redneck. your problem more than likely lies in a connection. may try pulling each wire off and reinstalling all together.

why whould it only be doing it under load

Rather than scrap the TR55's all together, I'd replace the #1 and #8 plugs and test and replace, if necessary, the accompanying wires.

replaced them and still feals down but hes runing 89 whould that have any effect

Yeah, when I put the TR55 IX's in I used Taylor Spiro Pros to replace the stock wires. Threw on some 100% Silicone heat shields too, but with coated LT's, it's actually cooler under the hood than it was with the stock exhaust.

Dang, he's cheating himself out of a lot of power, and risking detonation. I run 93, often with octane boost.
