I was wondering, Why do you need a dyno tune after headers are installed is it needed are can I do the tune with a hand held programmer?

Sorry mistake on heading. Why do I need a dyno tune after headers install is what I ment. Sorry.

You can't do everything you need with a handheld.


A dyno tune isn't a need after longtubes, but more of a want.

you really dont need a turn, i guess you can if you want, the only real upside would be that you can delete your rear o2s, and if it is a a4 car you can turn off low track. so it is up to you.

im putting in pacesetters lt's and tsp ory into the stock catback and im not going to tune mine, you leave a little power on the table and you have to look at that SES light but ill wait on the tune till i have a few more mods to make it worth it!

Dyno tunes are nice, but are not needed at your level of modification.

Your AFR may be off more than the pcm can correct on it's own is usually why. But to get the most power out of it you need to also lean it out from where the factory has it set for PE mode, and adjust the timing. Doesn't have to be done on a dyno though.

Your gains will be much better with long tubes. If you run a catted y and the stock catback it will still be very quiet.

you dont need a tune with longtubes...you arent going to mess anything up without a tune...if i were you i would wait until i got a little more mods under my belt before i went for the tune...if you plan on a cam do it then..and if you just plan for full boltons do it when you are dont with the boltons....no reason to spend all the money and then add something that throws the tune off ya know?.....as for the shorties....what year is your car...if it is 2000 and up (correct me if im wrong) they had redesigned manifolds that are basically shorty headers...so you would gain almost nothing with that..stick with the longtubes (or mac mids) and a catted Y...you will gain the power and still stay relatively quiet...

hope this helps!

What is "low track"?

To the OP, my car went from stock to the mods in my sig. i picked up about 20hp and 30tq from the tune, i didnt get the car dyno`ed stock.
