They say, a picture is worth a 1000 words:

That is 4th gear at 23.5 psi max timing is set at 12.5 degrees at 7,000 RPM. Boost is still falling off a little, so we need to address that.

Yes, that is a very close 275 WHP in 4th gear, stock turbo.

Goals:
1. 280 WHP 300 WTQ
2. 30 MPG
3. 13.5 seconds in the 1/4 mile and 105-110 trap speed
4. Reliability better than stock

Hurdles we are going to have to overcome:
1. Head gaskets are going to be an issue so we are going to have to watch the cylinder pressures very close.
2. Rod bolts are an issue. We may have to limit the RPM to 6900 with this tune and the rev limiter will have to be smoothed before hitting hard limits.
3. Customer relations. A clear understanding will have to be in place that you are pushing the limits of the engine... it could end catastrophic for the engine.

For 2013 and up to June of 2014 customers, this tune will not be available to you. Sorry, we simply cannot rely on the possibility of the early build engines new or old internals inside of them.

Thanks,

John

So this tune wouldn't be for a daily ?

100% daily driveable tune. Its just pushing the limits of the stock engine.

Although John no longer offers a 1.5 for 2013 owners. I had it on my 2013 for able 25k miles never any issues this car was my daily and I drove it every day for work and etc. occasionally WOT when other cars think I'm slow . But the tune is diffinately daily-able. And now with the new adjustments I can't even think of how much more smooth it can be.

 

[VtRally16]

Yea that sounds good I wonder if I went with the stage 1.5 could the guys at tork dial it back some for me to make sure I'm safe..I'm worried more of the longevity of the motor, would it be smart for me to just stage 1 it?

Well I'm out.

Nice! I really like that y'all keep the community informed in yalls progress and current problems your trying to over come. I feel confident if I get a tune it'll probably be a tork tune.

No boost or afr readings on dyno? List of mods with this tune?

Close to power goals now so that should not be hard. 30 mpg should be easy if driver does their part. But hard part will be not using the extra power to do so. If you can't run better than 13.5 in the 1/4 in that trap speed range with that power then something is wrong. More power and more reliable do not usually go hand in hand.

What is causing the high cyl pressures? Simply from tune itself or you think it's from restriction on turbine side? Rpms play hell on parts more than adding power does at times. Pull some max rpm, smooth those limiters, and turn tha wick up!

Would upgraded studs hold the head gasket better? I would imagine at this power someone would be making backup plans of getting a spare engine with upgraded rods, pistons, and a sleeve kit

 

[Manofdust23]

Well I'm out.

Me too. :sad:

 

[Rmas101]

What about those that know they have the upgraded internals? I don't see why more people don't check to see if they have them for 10 dollars and 20 minutes worth of time ::shrugs::

Edit: Yes - by upgraded internals i am referring to B pistons over the A piston. Not nec. new internals as thatd be a given !

 

[jp_vt2016]

very nice!

Yes, upgraded studs and head gasket will be beneficial.

No need to run sleeves, the factory sleeves are very thick.

Thanks,

John

This is a teaser, no need to post boost or AFR readings at this time.

We are working on the reliability big time. We have been able to address the LSPI issues very well and now that we are tuning for part throttle fueling, that will go a long way towards keeping the motor healthy under low throttle high boost applications. You would be surprised to see what the target AFR's are at 50% throttle and 18 psi of boost at 5k.

Cylinder pressure increase is going to come from cam timing and the added ignition timing. The turbine side has no impact on cylinder pressure. Max we have seen on the turbine side is 55 psi, which is running an undisclosed amount of boost at this time

Keeping the rev limit under 7k will be far from the limit of the engine. We have reved the stock engine out to 8200 RPM without any failure. Its the turbo running out of air that I am more concerned with over 7k RPM.

Thanks,

John

If you have upgraded internals, I don't see a problem with this tune.

At what point do you feel closing the deck and needing sleeves on this motor will be beneficial john?

Sorry bud, trust me... we are saving you the headache of trying to warranty out the engine. 2013's and early 2014's simply have had a ruff time with engine longevity.

Thanks,

He means, he looked with a boroscope and has the "B" pistons..

B pistons are the upgrade over the A pistons.

We have a few engines running some very high HP out of them right now, and we have had zero issues.

Thanks,

Nice info john! Teasers suck though as well as starting a dyno from 5k rpm! Lol!

Damn, 55 psi on turbine side, that is crazy! At what boost was that and what turbo? I know a lot of power can be had from lowering the pressure ratio on the turbine side from higher flowing wheels, headers, and housings.....
