LS1 Tune
Hi
My 1998 Z28 is running a little rough. I plan to take it into a shop, but know nothing about the LS1. What sort of items should be done/checked to an LS1 when doing a tuneup? Plugs, plug wires, O2 sensors, etc?
Thanks JA

How is it running

I have owned the car for 4 months. K&N induction, Borla catback, Hypertech 180 stat, B&M trany cooler and aluminum drive shaft. The car has about 45k miles on it. It's an A4 car. The engine compression is perfect (as per the report from the dealer I purchased the car from).
It runs pretty well, but at WOT just about when it shifts, it misses a bit/runs rough. I also seems to be a little low on power for overall performance. The idle is also a little rough.
I will soon install MAC headers/cat Y pipe and a that time I will replace the plugs and install new high temp wires and boot protectors. It was also recommended to replace the rear O2 sensore with Bosh units. However, I wasn't planning on replacing the O2 sensor unless I get engine codes after the headers are installed.
The car does not have any engine codes at this time, nor does it have any excessive smoke from the exaust. After the headers go on I was planning on getting a Vinci hand held tuner for a power tune, but I do not have it yet. There is no one locally that can custom tune an LS1.
Just woundering what sort of things I should be looking at on the LS1 when I do the header install.
Thanks JA

It wouldn't be a bad idea to replace the front O2's with a pair designated for the rear banks on a C5 corvette. Bosch part number for them is 13111 at autozone.
