Will I need to get a tune with long tubes, intake, underdrive pulley, and lightweight flywheel? I'm assuming the underdrive pulley and flywheel won't change anything and I don't plan on doing anything else performance related for a while. So do I need a tune to not damage anything, or is it just suggested for gas mileage/power, or is this not even enough to bother with? Thanks in advance for any advice.

definitely suggested, a tune will completely optimize your performance.
If you dont it will not damage anything.

all that without the LT's nope you don't HAVE to but it's neevr a bad thing. now when you get LT's and remove those cats, yeah you will need a tune pretty quick depending on your drivin habits

i did full bolt ons, then got the tune. gained a great bit of power

transamwes

hell ya the toothless ones give the best head also the cats and stock y pipe were the first things i took off to install the headers cuz it would be impossible to leave them anywhere close to their stock location with lt's. . .duh

You dont NEED a tune. I ran bolt-on's, stall, exhaust and didnt get a tune untill after H/C. The car ran just fine, 12.28@112.4x with no tune

agreed , tune after Heads/Cam unless you plan on never installing these things, then sure, get one, it will help gain some horses and the engine will thank you.

not to hijack but I’m doing lt’s on my car right now and I’m not going to run rear o2's, will the car run right or will it run really rough. and yes i will do a tune later

Car will run fine. Rear O2's just tell you if the cats are working correctly. You will have an SES light but will not hurt anything. That's what I am doing right now. Haven't gotten the codes tuned out.

transamwes

yup left mine off unplugged rear o2's drove to the exhaust shop with open headers and had a custom ory welded in. . . car runs fine without the rear o2's

Alot of places will do retunes for a reduced rate or even free if you do it once. Maybe find a place like that and take advantage of it through every step
