Cadillac STS-V Series Forum Discussion, STS-V Ghost Tune Video: What Gives? in Cadillac V-Series Forums; Ok, what's the scoop on this? I know about the other tuning stuff like madtuning, but have never seen a ...
That guy is in Pittsburgh. Does a lot of LSx tuning. Probably messed with the VVT to give the choppy idle effect of having a cam. Lots of places tune the 4.4 LC3 N*. Only hp tuners has the 07+ LH2 and only madtuner covers the 05+ LH2.
Which do you prefer if for performance for the +07 LH2? Assuming the car is stock. There's a wicked sounding late Camaro SS with the license plate "NA" running around with a tune that is chopper... or it's just got a very long duration cam in it LOL. Either way, it would be cool to roll up to a light with a q-ship STS with an idle like that.
...So I asked Domin8 Tuning about this tune. Here is how this went for my LH2.
Hi James, as long as our software supports the ECM in that car, it would be possible to do (2007 and up only support the 4.6). But, to notice it, you need a very free flowing exhaust and no cats or high flow cats. On cars that still have stock cats and a quiet exhaust, its not as noticeable.
Any other questions, let us know.
Thanks, the car is a equipped with a Corsa catback, and Volant intake system, so It does have a little rumble to it.
Not sure that qualifies as not stock though. Does the tune increase performance as well?
With the corsa exhaust, you should notice the cam lope...
A typical tune will net you approx 15 - 25 hp, but the trans tune is where you'll notice the most improvement. By adjusting the shift points to keep the car in the powerband, the car will feel much more responsive, etc..
As for price, street tunes are $250 and a full dyno tune is around $500.
Any other questions, let me know!
What about gas mileage? How is this affected by both tunes? Does it go up or down? Also, is this something that I can complete on my own? I am looking to improve the mileage as well.
Typically a tune should not drastically change the fuel economy. Best case, it might go up slightly, but shouldnt go down. Now with that said, everyone gets worse mileage after a tune since they are enjoying the new power and pushing the car harder! But once that wears off, everything should settle back down lol.
A tune can also be geared with fuel economy in mind too. Instead of raising shift points etc, they can be lowered and have the converter lock earlier. That will help get a little more out of it, but the negative is that the car could feel a little less reponsive, and lug a little more.
Unfortunately there's always the catch lol. More power/fun typically comes at the expense of lower mpgs.
I actually do not do any "remote" tuning at this time, and instead spend a few hours hands on with each car working with the owner to dial everything in for them until they are happy.
Are you located in pittsburgh?
No sir, Cincinnati.
Yea, that might be a little far!
Not to lose a customer, but I know that the guys at Cincy Speed have knocked out some great work over there, and right in your area.
Good luck with the car & feel free to ask any other questions!
Just in case anyone on here cares to know about it.
