3.3TT Kia Stinger Aftermarket Exhaust Information and Discussion

I've only seen few people on here have boost creep or over spooling issues. Basically, the wastegate actuator doesn't signal quick enough to bleed off boost over the target generally when under more load than normal,comes such as going up a hill, downshifting into just the right RPM to cause significant load on the turbos ect.. I'm pretty certain it is a tuning issue. Unfortunately, most of the the tunes have catalytic converters in place or at least the primaries. Maybe contact the tuner with some data logging if that does happen to you to see if they possibly could correct it by sending you a remaped tune...

Have you seen a post on these forums about a fix where people adjust the wastegate? If you have please post it.
 
Nobody has done it yet in the US.
 
What is the definition of a heavy pull?
When you come out of a corner and hit the throttle hard and you feel that power hitting strong : heavy pull (high torque values ) then the limp mode strikes
 
From interior to exterior to high performance - everything you need for your Stinger awaits you...
I think that's fine...
 
I am looking into possibly a bigger set of Turbo s , that spools up a bit slower to fix my problem with over spooling lol

Nobody has overspooling problem with so few mods.

Do you floor it at low RPM? thats very bad for any turbocharged car.
 
Maybe I missed the history between you two or the implied winkey wink wink. It's pretty bold to say somebody does not have a problem that they have talked about having for about a year.
Piggy back tune, Intake, FMIC, secondary downpipes, and cat back... that is everything but the primary deletes.

Primary deletes pretty much guarantee the issue (if you have all the other plumbing opened up) so perhaps his car is slightly more sensitive.

No it will do the same thing when using launch control as it will over boost or spooling within 2500 to 3k under heavy on the gas lol just check for tuners in Vancouver area and no one is turning the stingers:(

Oops. I think mistook him with the member that had overspool with only a piggyback and intakes.

I talked to Jags at ECU tuning via email and he told me the following:

We’ve done these before. The gain was just over 50hp 88lbs tq. I’ll find the dyno sheet this week (we’re in the middle of uploading all the sheets onto a cloud).

Price is $795. It has to be programmed on the bench.

Regards,
Jags


Maybe I'll drive out to their shop for a chat and see what they say in person.

FYI-That must be a very mild tune as Kagantuned has already made over 90whp gains on a completely stock Stinger with stage1 tune and he’s expecting 420whp/450wtq before he releases it officially. Kaganader Tuning on Instagram: “Had a little free time to test out the latest revision on the awd Stinger 100% stock no mods done and it has put down 409whp and 450tq so…”
 
@TorkMe just posted on FB that they are looking at doing a back end flash for users of piggybacks. Should address the issue @Arnie War has and more.

KIA Stinger 3.3 "back end flash"... who wants one?

Now, some of you may be wondering... what is a back end flash. Well, that is a flash you use in conjunction with a piggy back or some other type of signal modifier. I have acknowledged that the Stinger market is not going to get rid of their piggy backs, so we have made the decision to fall into the fold (or something like that) to get your guys cars running optimal with a piggy back.

What will our back end flash address?

1. Shift improvements. We will adjust shift timing and stop ignition drop. Thus speeding up the shift recovery, this has been good for .2 seconds in 1/4 mile times.

2. Increase torque limits, this should stop the throttle from getting closed on shifts. We have seen a lot of piggy back datalogs with the throttle closing on shift or the throttle closing in the higher gears due to torque limits being exceeded.

3. Tops speed limiter increased for those who have a 135 MPH limiter we increase it to 170 MPH.

4. Target lambda (air fuel ratio) will be set to one of the selected options you choose in the menu when ordering your tune. We will have 11.4/11.8/12.0 as options for your desired AFR ratio's. Custom AFR/Lambda targets will be an additional charge.

5. Stop cat over temp protection from kicking in and raise the fuel correction for turbine temps. We will have catted and catless options for these correction limits.

6. o2 code for catless/race cars cat delete.

7. Turbo speed limits increased (calculated not actual) to allow the full ignition spark delivery, so you no longer have to gap your spark plugs down to the .021 or smaller to get the piggy back to work properly.

8. Increase in coil dwell time to aid in proper plug gap and reduce spark blow out. This will allow for larger spark plug gaps to be ran without spark "blow out".

9. Increase max air flow limits... to stop the sudden "dead throttle" from happening when pushing the limits of the piggy back boost levels.

10. Low fuel torque limits increased to standard limits, so you can run at 1/8 of a tank when at the drag strip. This will not stop the factor fuel system from running out of fuel, or the fuel basket from getting sucked dry (fuel basket is the reservoir inside your fuel tank).

I need some feed back from the community if this is something they want us to offer. Starting price would be $495 (damn steal) plus shipping. With options, it would price out to $695 (custom requests from customers). We would not set or change anything in the boost management or ignition management, due to the piggy back controlling those parameters, but we can address all the limits that currently hold the piggy back from being utilized to its full potential.

Please let me know if you would like to see this as an option for the 3.3TT Stinger models.

Thanks,

Tork Motorsports.

Interesting indeed :) maybe this would fix the over spooling since I only have the primary cats left on :)

Very interesting

Also Kagantuned i believe in NY is getting great results so far and already made about 410whp/450wtq on a completely stock Stinger.
I asked Tuners in the Vancouver bc Area and it seems no one is tuning Stinger ECU as of yet there :) I will see if Tork Motorsports finished their stage 2 tune approx 21 psi perhaps or try the back flash for piggy backs :)

What is (supposedly) the stage 2?

The stage 2 is a very aggressive tune , close to a target of 200 hp gains above stock , geared more for track with clear exhaust:) I would be happy with 100 whp over stock on my Awd Stinger GT or close to that :) and no limp mode lol
 
I recently replaced the stock muffler with a JunBL EVC. It is quite loud now. :ninja:

Little sound clip with open flap :
(This is not a WOT pull, I am just increasing the RPMs to 3.5~4K)

Now the exhaust line is a true dual but I may add an H or X cross over later on.
