Should move the curve around and gain 15-20hp/tq max. but to throw the curve is totally worth it
is it going to lower the curve or will be more topend?Should move the curve around and gain 15-20hp/tq max. but to throw the curve is totally worth it
By the way, no one has ever bought these for an ls here right? Did Quik buy some or make his own, I remember he ran some test on headers to see the gains.

Nice score Alax,
I think you are one of the only people to have this mod!
Quik had some shorties made which is why he only saw a 5hp or something low increase, waste of time to do all the fab work and only make short tube headers.. 240sx rules all
Alax, being as you are tuned I suggest that you contact Ills and work with him on a new tune for the headers. With the torque curve moving it would be good to let the computer know as it wasn't calibrated to handle this issue. People can debate this but being as you are already tuned it cost you nothing extra(or shouldn't).
Also it would be nice to see what happens on the dyno, definitely pay the extra for wideband as this can help Ills better with his tuning. It will also make sure that you don't run lean as is possible with headers or to rich in cause the computer decides to try and dump fuel to compensate. I don't know much about this ECU so I don't know how it will react.
i would, but i assume he's still too busy and not doing tunes again yet.plus i can just get it dyno tuned here for 400 after i install the headers.
When I did the dyno run before and after the magnaflow exhaust, the guy told me 400.
Dyno run cost 125 for 3 pulls, they gave me 3 before and 3 after though.
Dyno tune cost 400, they dyno it, change whatever they do when tuning the car, dyno it again to see how it went, change things a little more, dyno it again, squeeze some more power out of it, dyno it again and tune the tranny and whatever else they do. A full blown dyno tune, not just a duno run
That's a pretty good price. The one I got for my SRT8 was 6 bills, down in Delaware not this ripoff city NYC.
Hey let me kow when you go so I can see them in action.
