The only original reason to get GMS1 and then tune over it was to be able to reliably make more than 22.5psi. Trifecta's Infiniboost tweak changed the rules to where it was no longer needed.

So where does this leave us?
HPT: It will still be helpful to have the sensors. It is possible to buy the sensors and wiring and install them yourself if you already have the sensors or don't want to buy the whole kit and pay for labor.
Trifecta: It's a wash. It's nice if you have it, but not needed.

 

Why would you push the little turbo over that?

Have any links to the used HPT setups?

 

idk thats what all the cool kids do though

 

If peeing your pants is cool consider me Miles Davis

 

Oh I love your work!

 

Thanks.... I try...

 

I am looking to have my local dyno shop use HPTuner on my car the end of this month, is there anything I need in order for them to tune it?

 

do they already use HPT?

 

Yes they just haven't touched a ss/tc or a boosted balt period, but the guy doing it used on his 03' sc vette, he has a lot of tuning exp just not on a balt lol

 

Because it makes more mid range Tq and whp.

I turned mine back to 23 psi now from 26 because the top end is a lot better. 60-80 times are the same as it was on 26 psi so midrange acceleration is still the same regardless.

Be careful they might not understand how different the GDI turbo engine reacts to A/F and timing.

 

I myselkf now have the GMS1/Trifecta dual tune. I recently switched over from a pretty good HPT tune. the reason? It really appealed to me to be able to putput around town in the GMS1 tune knowing it wasnt being so hard on the engine. Then, when I need it, I can swith over to my stronger tune. I like the idea of my engine not being driven 24/7 in a high powered tune.

Listen to Term2. If you go to that shop make sure they really know what they are doing with the LNF as far as timing and AFR goes.

 

I can put put around town on my track tune... it's all in how you drive your car.

 

X2. My car drives just as good if not better than stock.

 

No argument here. Its all in the driving. But it depends on the tune too. My old HPT tune had some tq management going on for the track and launches which was great, but it kinda suked having to drive around in it all the time. You cant argue against the fact that being able to switch from tune to tune is a great option. For me, I just love the way the car drives stock. Then, I hit a switch and Ive got gobbs of power at my disposal.

Theres always going to be arguments for both sides. It comes down to a matter of preferance.

 

I run the same tq management at the track and on the street, the only time I change it is when I run the DR's on the car. Guess it's all in the HP Tune at that point.

 

 

Cool. Well thats where I had issues. I could def tell the difference between stock and the HPT TQ management and I liked the stock feel the most. Since I dont have HPT access 24/7 as you do I couldnt just load my preferred tune whenever I wanted. I have two very distinct wants in my tunes. I want stock feel/power for driving around town and a powerful tune for the track. Trifecta allows me that.

Anyways, were going a little off topic now. I guess the OP has enough info to make an informed decision based on his needs and wants.

 

I can do that, I thought you had a specific... Thanks though

 

LOL! Trying to be a lil funny!

 

LOL I just now clicked on the link to see what was so funny. Nice one

 

Mine drives just like stock or better. I have very smooth DALs I run that helps.

 

No worries, everything i find is normal price or already sold.

 

I can see it now "damn this bitch is lean, lemme richen it up to 11.5:1 afr".
KnightSS/TC: if they never tuned an lnf then stay away.

 

^this

Ive been tuning cars for about 10yrs, this being the first Direct Injected and it really is another world!!
