Just installed set a Kooks a few days ago started up ran great no engine lights, didn't let it run long got it up to warm checked everything out it's all good, moved it out of my driveway and just took it for a drive around the block everything seemed hunky-dory get it back in my driveway and open up the NPP and I blip it a bit, get it up to 2400 and I got a nasty vibration in the shifter like it just bouncing if I hold it there it's just going to keep shaking can't figure out what it is, there's no missing the engine and no exhaust leaks. Anybody have any ideas let me know please thank you

You installed LTs and didn't get a tune? Things are different with LTs on the car and tunes are usually the accepted necessity for a smooth running car.

Yes i know Elmer. Haven t done it yet. Have installed them on c5 and c6, never experienced this before. I know is LT is a different beast. Will do some sort runs and idles, may smooth out a bit.thanks for the input
