Is it a bad idea to run headers without a tune??

headers were 400. tune was 350. headers u can barely feel compared almost all the other mods.

tune, intake/tb was the best of all mods

But on our cars the header and Tune is by far the best bang for your buck for HP/TQ gains. Everything just is gravy(catback, OP,FP, and intake)

just saying... its not the first car that ive modded

and im sure the tune will make more power than headers...

show me dyno #'s prove me wrong. dont just talk shit. lets see facts

Where are you getting your facts from? You want to see dyno gains from a header alone, there's tons posted already for you to search for.

A proper longtube header will give better gains alone, but if you add a tune the gains are even more huge (like +40wtq where the dip used to be, etc).

A tune will give you a bump in power, but the biggest benefit is the throttle response, better mileage, etc. The only way you'll make more power from a tune alone vs a header alone is if you're running an e85 tune with e85. On pump 91/93/94 octane you won't get massive gains from just the tune.

im not saying your wrong about that maybe you are correct. i havent seen dyno # on either one.

what im saying is a race. like compare auto x times. or a track time. or maybe a 0-60. the tune will not only add power and torque but like u said throttle response and from what ive read about ecutek tune a few other benefits such as launch control. so u could be totally correct for all i kno. but i dont think we will have a perfect answer. i think we all kno if your planning on getting a tune and headers that u get the headers first.

They are pretty damn even. But together they will make a big difference. Add E85 and its a significant bump in power.

I think FA20Club will give you the best bang for your buck on EL side. RevWorks on UEL side.
