tahoe with lt headers
hey guys i just recently purchased a set of lt headers with ypipe from a member on here should be here on wensday im in the process of learning as much as i can as far as performance..i currently have a CAI, corvette servo, flowmaster(will change soon) any other muffler you guys suggest that flows alot better, what about magnaflow? i also ported my throttle body and thats about it..it has stock 3.73 gears and im running 24s
i dont want a to make this a race truck but i do want to get alot better torque and some hp.. now will the lt headers add a noticable difference? i will be getting a tune in about a month also, going with black bear..any other suggestions are welcome

Headers combine with a good tune definitely make a difference. I would drive easy (no WOT) until you get the tune. I have an Airaid MIT air intake, headers, ORY, and tune on my Tahoe and it's much better now.

You don't need a tune for longtubes honestly. And the headers won't change ur tune in anyway if you have a previous tune. The only need for a tune after headers is to delete o2 sensor codes and for more power of course. Drive it like you stole it.

Sorry, but I have to disagree. LT headers indeed changes air and fueling parameters. If it didn't, there would be no power increase. You really need to get retuned. Until you do, you are leaving half of the potential power gains on the table. Again, unless you have a wideband or have a way to check WOT air/fuel ratio (or at least monitor the fuel trims), I would use a little caution until it's tuned, especially since you've done other things too (i.e. CAI, TB porting, exhaust mods, etc.). I'd hate for you to run it lean and damage something. You will be okay with normal driving, just try (I know it'll be hard) to limit WOT until it's retuned.

Yea I'm sure it does change slightly but doesn't seem like it'd be enough to have to drastically change driving style or need an immediate retune. Atleast a local tuner here said no need for a retune after I got my old ride tuned and later put lt headers on.
