You can adjust your WOT a/f, timing, rev limiter, gear ratio, wheel size and more.

 

now is that a good idea to go around changing that on my own or not?

heres my dyno sheet with the a/f, what would you recommend changing it to?

 

Personally I wouldn't change a thing myself, I would call Brent up or someone at Brenspeed let them know your problem- Send them the dyno graph with A/F and see if they will modify your tune for you.

 

Must be nice living in texas where longtubes are legal. no cats either?

I hate you guys...

 

Im running cats

 

if that ends up costing money, i dont think it would be worth it to do that

i guess i could always just go up by small increments and experiment

 

Call Brenspeed and see what they suggest.

 

No restrictions here........ in fact I got pulled over and complimented for my exhaust last year.

Sissy.....

Not a good idea experimenting on a tune that controls a ~$4000 engine. Just my 2 cents.

+1.

 

lol never thought of it that way!
but also, since i'm just raising the a/f ratio, isnt that making the tune safer, therefore harm to the engine isnt possible?

also, i was messing with the xcal 2 today and when i press program vehicle there are only 2 options: 93 octane tune or return vehicle to stock. where are the other options? do i need to unlock it or something?

 

If by "raising" you mean taking a 12.8 to a 13.5...... that's not a good idea. Raising the a/f means more air, less fuel to the engine. Air is what makes power, fuel is what makes it possible. Too much air means bad things; more so if you're supercharged but still, not good for any engine.

I'd consult your tuner and see if there's a charge; while you're on the phone, ask them about the additional tunes.

 

got it, i'd take your advice over mine any day lol

anyways, so if i already have a 93 octane tune, can i add another 93 octane tune with different settings on the xcal and be able to switch back and forth?

 

Sure, just have to call them different names..... example: "93 R1", "93 R2", etc. etc. etc.

 

does any one have the BBK longtubes, catted x pipe with SLP loudmouths? just wondering how it would sound..

 

I'm sure some would fear the gates of hell had opened, others would think it sounded like a symphony. Personally I'd fall into the later category.

 

Ive heard a GT/CS with ARH LTs with catted X and Loudmouths and it sounds Fn sick!! Very loud, but not extremely deep- Has a sort of Race tone to it.



Ill see if I can dig some videos up

 

 

great, i tried looking on u-tube but found nothing, i would love this set up!

 

I have that exact setup with stock GT mufflers and love the sound.

 

this is all i could find on youtube
american racing long tubes, x pipe, and lm's

all he does is turn it on

Sounds amazing!

But, I would probably get very raspy at higher rpms.

I have LMs on the 07 I just bought, sounds ok. Not a big fan of the motor boat sound they make at 4k rpms in 5th gear...
