I am finally doing my LT, MM, and Cat swap next weekend and I want to know:

1) Can I drive my car after removing these items without a tune with no issue ( other than SES light)

2) OR should I remove these items the day before my dyno ( have no idea WHEN that will be but it will be this year)

Thanks in advance.

I drove for over a year with all those items removed with no problems, car ran better then stock to me, only problem was ses light

Ive been rolling around since november with no air or egr. The only thing ive noticed is the ses light and the extra smell of gas lol. Im just to cheap to pay for a dyno tune and to busy to let my car sit for a couple days while the ecu is out getting a tune.

I plan on doing this very soon, I had just figured on having the SES turned off for the air and egr codes, then once I finish my other small projects, I'll get a dyno tune.

But will I hurt my cats Or anything else driving it without a tune if I remove them

No. You'll be fine.

I drove my 1st LS1 car 2 years with emissions deleted and no tune and there were no negative effects
