What would you do? GMS1 then Trifecta or just Trifecta
Okay,
I was gonna go ZZP canned, but with a little more research and asking questions, I've decided Trifecta is a better route.
Soo...
I looked at Trifecta's FAQ's spoke with Vince via Email and here's what he had to say about going GMS1 then Trifecta.
He did give me a lot of information. This was just one part of the email.
So with that being stated from Vince, I'm not sure what I should do.
Do I get GMS1 for the new sensors or do I get the Trifecta and start feeling the benefits right away?
If I go GMS1 I would have to wait until Fall or maybe even Spring for it. If I go Trifecta, it'll be sooner.
Thanks for your input

If you are asking my opinion, I wouldn't spend the money on the GMS1
upgrade if you are ultimately going to tune with us. There is absolutely
nothing to gain by having the new sensors. There may be people saying
different, but the rules don't apply to us the same way they do to others
because we have more control over the tuning parameters than anybody else
besides GM. The only advantage to having the sensors is they don't seem to
fail like the stock sensors do, but only some people have problems with the
MAP sensor failing (which has nothing to do with the tuning - stock tuned
cars have the same problem). Others have run a tune for years with no
problems.

if you want u can just buy the sensors install them and have vince tune you for them. no need to buy the whole GMS1 kit i'm 99.9% sure you can just buy the sensors elsewhere and save a PILE of money.

yea but im worried about what will happen if i have a intake and downpipe on with it too. theres a lot of ppl having problems with gms1 + bolt ons. if i go trifecta im only going a mild route. i want a 20psi tune. i want the max power i can get only from 20psi tho. if i want more power after that ill just buy another turbo and bolt that on there. lol. this car has to last me a long time.

You don't have GMS1. You have a trifecta tune. One of your options is similar in power to what GMS1 is, that's all.
What you said is confusing, which is why the next guy said this.
Dart, if you go with Trifecta, you can get the best of both worlds. GMS1 style power on one setting and a more aggressive tune on the other setting. You don't have to worry about problems with bolt-ons because the tunes will be logged and adjusted for your mods.
Hope that clears things up.

sounds like a good idea. well see tho. im content in driving around on stock tune then hitting the tc button for some pulls. im getting stock tune friendly mods like the k&n intake since it keeps fuel trims in check, and a catless dp. then some supporting mods like charge pipes, maybe a diffrent intercooler since ours are so weak and always cause boost leaks. motor mounts too. i already have the TTR upper engine mount, not installed yet tho. id like to get a catback too, but thats more for sound since gains are only like 3-4whp. lol.

yeah im going 2nd PCM n tune of some nature no other way to be 100% sure that you wont be caught... people say trifecta is 100% undetectable... for now... its just a chance im not willing to take n for what another $200 i know for sure its undetectable... thats worth it to me for sure!

not sure i know you have to do a security re-learn process that's a bit annoying however u only do it once when u swap the PCM in. i got my PCM on the site in the classifieds... they are damn near impossible to find new now

If i had it to do again... Would have just Trifecta tuned or HPTuned and called it good.
There have been other problems. Issues with the boss on the map sensor not being trimmed correctly(or at all), i have seen a lot of flutter from GMS1 cars as well.

So if I get the Trifecta Tune and get fluttering does that mean the sensors went bad. If not, I guess I don't understand how GMS1 gets fluttering from the 3 bar sensors
