So I have made my mind up and have decided to get tuned via Trifecta. My question is if I get a stealth tune, does the car run stock when I have the tune turned off? Will my mil come on still because of my fuel trims and my intake and dp.

 

No the tune adjustments work in either mode and the fuel trims are the same either mode tune on or off.

 

I think the only difference is when tune is on its more aggressively tuned, when off its tuned to be like stock but without the issues ud have with stock

 

ok so essentially when i hit my cruise control button it will just raise my boost? I already have gms1 which hits 21-22psi and im wondering if i will notice much of a jump? I am fully bolted right now. I'm not looking for a big jump in power just looking for better stft's and smoother power delivery as well as a bit lower wot afr.

 

The car will essentially run the same when the tune is activated or not. When it is not activated, the car should perform how it does now without the tune. When it is activated, it will run on the boost levels (and timing) of the Trifecta tune. A 24psi Trifecta tune should feel way different than GMS1 for sure.

 

The tune is always activated, you just choose which two boost setting you want. The software Vince puts on your ECM is proprietary. It's basically his own operating system. He can put any boost settings you want for either tune, but your GMS1 tune will be written over. I repeat: all stock software is over-written.

 

Big difference between GMS1 and the Trifecta Tune! You'll like lots.

 

I just got the budget tune this week, and I was GMS1 before.
Anyways I am selectable via cruise, when its on I am on GMS1 tune basically, it performs no different than it did before. Cruise off and its trifecta, I feel the difference instantly, spool time is reduced, boost comes on quicker, the car is a monster..

It is kinda like having a nitrous button, I don't run mine all the time, just when I want to have fun and feel the power.

 

OP. If you're fully bolted get the regular tune.

 

Yeah I've been pm'd a few times now and I'm being told to go hp tuners? I like the idea of switching your tunes with a button and from what I've read they both perform good. I also like the new idea that trifecta came out with for our stupid maf issues.

 

im tuned by trifecta and full bolt ons except for intercooler and my car runs great! he was pretty quick about getting my tunes to me and fine tuning it after i data logged and everything. i would definitely recommend.
Side note: i see your name is balt and vette...i have an 08 tc balt and a '12 grand sport vette with headers, intake, tune, lowered, blacked out, etc... haha so cheers to us!
anyways...sorry to get off topic haha

 

Ya Im running his ecp tune and it runs great and I have a bov. no MAF issues

 

oh and 1 thing youll notice over the gms1 is the no throttle delay from trifecta if you request that.

 

this is nothing out of the ordinary;
Most of the HPT guys are very pro-HPT, and will knock Trifecta at any chance they get.

HPT doesn't offer the stealth or selectable tuning options - so after those features, it comes down to the tuner ~ and can be argued that it's very much the same thing.

If you were a local, I'd strongly encourage you to stack the options and make your choice without anyone else trying to pressure you.

 

Enlighten me on this, I never knew and I want

 

Can u run a bov without relocating maf with this tune? Like just stick one on an good to go?

 

yep

 

ya You could run the bov either with bov and the bpv or just the bov and itll work without a maf relocate. vince told me that you could either put it stock location or in the relocation spot it doesn't matter with the ecp tune. I was thinking about running the bov by itself but ive heard if you do that you get alot of surge...I dont know if thats true though. I may give it a try soon once i get a block off plate. and the no throttle delay...Its no throttle delay. It just much quicker throttle response. I dont know if thats a special request or if thats just standard with his tune but I put it in the special request spot. Its much improved throttle response.

 

I know exactly what you mean about the throttle delay with gms1. I've been in a trifecta 24 psi tuned car and noticed the throttle response was excellent compared to mine and had much smoother ramping. The boost came in nice and smooth and helped out with traction a lot which is exactly what I want, smoother power, better afr's, and an overall happier car. I just pulled my intake manifold off and noticed a bunch of build up on top of my intake valves so I have to pull the head off sometime this week. Should be fun lol.

 

I have never been one to tout merit's of any 'mechanic in a can' item;
but I hear some people have god results with 'seafoam'

Ya I've seafoamed my car every 5000km and to no effect. I think if it's done from day one it would help but if you already have gunk caked on it's not too effective.

 

I'm definitely not one to knock Trifecta. I had the stealth tune for a year and thoroughly enjoyed it. I used 20/24 psi and had a blast with it at the push of the cruise control button. I only switched to HPT because I wanted to learn to tune and because I wanted to be able to log. I do miss the switchable tune, which I still have on another ECM, but I like the logging capability. Trifecta is great for the average guy who just wants to drive his car and have fun with it. HPT is for the guys who really wanna get in there and **** **** up.

 

as funny as that is - there's more truth to it than some might care to acknowledge

 

I'd like to point out that Vince is a programmer first and a tuner second. He's even admitted it. Secondly, its quite well known that he tunes very conservatively. Almost to the point of the cars not really running as well as they should be. I've not ever met an actual tuner who didn't laugh at Vinces tunes.

I don't have anything against him. Just posting what I've seen and noticed. I've never lost to a trifecta tuned car that's for sure.

 

get a real tune..HP tune that is...lol
