Dyno numbers on my ‘16 GTS with Pure Turbos Stage 2 (Very disappointing)

Hello all and happy New Years!

I have been wanting to post about this for some time now but haven’t got the chance.

So about a year ago I picked up a beautiful CPO ‘16 GTS with only under 6k miles. The car is super clean and has almost every single option ($157k sticker). I started my project just a few months later. I took my car to SSR and my car was done and ready for pickup by the end of March.

I installed:

Pure Turbos Stage 2
Catless DP‘s
Golabworx Tune

Upon startup the car sounds very nice and beastly. I was expecting a huge power increase on the ‘butt dyno. The car felt very strong but did not feel the huge increase I was expecting.

I was told by Pure Turbos and my tuner to expect around 650 whp with the crappy 91 California gas we have here.

It took forever but finally about a month ago I finally got the chance to do some runs on a local dynojet.

I had extremely disappointing numbers. Only 566 WHP and around 604 torque. Those are numbers on a car with no turbo upgrades. Only catless DP’s and a tune should produce those numbers. Horrible.

I really was expecting around 650, I’m about 100 hp less than where I was expecting. I am not running meth but I may do so if needed.

I need to take my car back to SSR now and need to have them check for any boost leaks as well as the wastegate to make sure I’m getting the maximum boost.

What do you guys think is wrong here? What needs to be done? If I would of known that with the 91 gas I would get such poor numbers I would have never gone with Pure Turbos and I would have gotten the same numbers with just catless DP’s and a tune.

Something is off mechanically or with the tune. Did the dyno operator tell you how much boost the car is making?

I've seen dyno of a Eurocharged car make ~675whp with those turbos and 93 octane so the numbers Pure gave you sound right for 91 octane.

Hopefully someone can help you with a good mechanic in SoCal.

Did you check/change your spark plugs? Do you know what the smoothing was set at on the dynojet? That dyno graphs looks pretty wavy up top.

I did upgrade my spark plugs. Don’t know about the smoothing. Will check on these.

They did not hook up the boost line so don’t know how much the car was boosting.

A dynojet usually has smoothing factor from 1-5. It should say on the top right of the dyno sheet you posted a picture of next to STD/SAE correction factor. Usually they print it with a 5 and it looks a lot smoother.

Most Pure Stage 2 turbo cars make peak power at ~7000rpm. You car seems to be making peak power at ~6000rpm.

I am definitely not a tuner or mechanic but I was guessing something with the ignition system based on those two things.

looking at the dyno graph it appears traction control is kicking in or you are spinning the tires. Start with the tuner.

We made sure to put the car into dyno mode so not sure how traction could be on 😕

Since you paid them for a tune, I'd start by calling Labworx. They should have some suggestions. Looks like they've done several of these cars with Pure Turbos.

First off never tune on a roller dyno, what you need is a hub dyno like Dyanapac in order to get proper load bearing numbers.

Wasting all that money and warrantee just to go straight won't do anything for you in the canyons.

He never said he tuned on a roller dyno. He went to a dyno day to get dyno numbers.

As usual, no matter the thread topic, you interject with a worthless comment about DA CANYONS. You might want to send a memo to Porsche, AMG, and other manufacturers that more hp doesn't make your faster.

Maybe it's because the poster drives the canyons too with his GTS.
Yeah tell that to Lotus when lightness makes you faster everywhere, more HP just makes you faster going in a straight line.

Oh sweetheart it seems Pure Turbos do their tuning on a roller dyno...Dynojet

No one has any Earthly idea what you are talking about.

Thread starter went to a dyno day. You told him not to tune on a roller dyno. He didn't say he tuned on a roller dyno.

Then you posted something about Pure turbos tuning on a roller dyno. Pure turbos isn't a tuner. They manufacture turbos. Different tuners use different kind of dynos. Precision Tuning and Eurocharged are tuners. You can get an Eddy Current dynojet that simulates load. Or you can use a Mustang Dyno. Or there are other dyno models/companies. They are all still "roller dynos."

I'm about sick and tired of your nonsense dude. You are completely clueless.

Didn't you purchase the turbos from SSR? and pay Labworks for a tune? Not to be a dick but they should be helping you if you spent all that money with them.

No one is going to be able to figure out what's wrong with your car over the internet.

Sorry sweetie but no one does serious tuning on any roller dyno, no one.... It's ether engine dyno or hub dyno for accurate engine loading.

And kiss my old *** chump..from Pure Turbo's website.

Yeah tell that to Lotus Porsche Ferrari McClaren as they try as hard as they can to make their cars as light as possible before making more horse power..
Lighter with equal horse power is always faster but you know better...

For the record...my old GTS was built by Eurocharged ATX here in Austin. The car made exactly 650whp with Pure Stg II turbos, Eurocharged downpipes and a Eurocharged tune. The car ran REALLY well. Tons of power and zero issues.

Thanks for the info. You have 93 pump gas I’m assuming in Texas right? Were you Running meth as well? If 93 octane gets you 650, I should be getting at least 620 without meth and running 91 no? Hopefully I can go down to SSR this week.

Did you get rid of it? If so, what did you replace it with, if anything?
