sooo i have a full 3inch turbo back from dejon, maf relocation to before the throttle body, tialQ bov, big fmic, and a tune from vince for 20psi and 25psi.. idk if vince died or what but he wont respond when i email him asking him to look at my data logs so i figured id try my luck here. i had this problem about 3months ago because the plugs were in need of a change.. so know the new plugs did great at first but tonight the car just started acting up again and ive pretty much got to the point if i cant figure it out im selling the pos.. i do love the car but the constent stupid bs has finally taken me to the max.. the plugs are ac delcos idridium gapped at .20.. any usefull information is greatly appreciated.. usefull being the key word.. thanks again a

 

Well, .20 is gapped too far. They need to be gapped at 0.030 to 0.035.

 

.25-.20 isnt too far for big psi..

 

He don't want to listen let him.sell it

 

well vince told me to gap them at .20 so i did. they have been gapped at that for 30k miles and i havent had a problem untill tonight and the time before this. so if you guys think that it is wrong ill try it.. so honky if wats your oppinion? u think that its off too?

 

I think they are gapped too close too, or the gap has changed

 

Has it rained recently?... Hear me out...

The blow-through MAF setup has proven troublesome in some cases, such as when there is moisture in the IC, after it's been humid or rained.

 

i did rain today but that was after i drove it. but it would make sence since the air is humid befor the rain. and yea it would be nice if the gap was wrong. i will try the .30 gap tomorrow.. thanks guys i appreciate it! i will let you know if the gap helps.

 

Well when you're driving around in humid weather the turbo compresses the air, but the air also heats up allowing the air to continue holding the moisture. When the air enters the IC though, it cools and condenses, causing water to be released from the air and build up inside the IC. Then as airflow is rushing through IC, the water hits the MAF, throwing it off. The stock IC has a water condenser/collection bar on the bottom for this reason.

Yeah, closer to a .030 would be a much better gap.

 

Im at 23psi by ChevyCobaltss3 and I am gapping mine today to .032

 

Im sticking to my .35 gap with my 23psi tune like Vince says lol

 

thanks alot guys going to try .30 now..

 

Yeah, I'm at .032 too with S1 head and cams, fyi.

 

I'm at
Stock gap on 24 psi no issues

 

The .30 gap didn't work. Still sputtering and spitting sh%t sux.. gunna try the .35 gap tomorrow ill keep u guys posted... Any other thoughts are appreciated cuz im totally stumped...

 

Gaping it higher isn't going help. Can you take vid of what the car is doing? Also what did your plugs look like when you Regapped them? Also how many miles do you have on the new plugs?

 

Could be fuel trims, but you can't post a log from Trifecta. That's one of the reasons I got away from it.

 

I was thinking that as a possibility too. OP if you have an intercepter you can check your ltft and stft.

 

I have about 50miles on the new plugs. And yea ill try to video it. It's weird because last time this happened i pulled the battery to just do a soft reset and it didn't help.. so i just reflashed it Wen i put these plugs and its been running great untill this.. so maybe its some kind of error in the tune or glitch.. I'

 

OP, run some logs and send to: Logs@WOT-Tuning.com

 

Well u guys are gunna b like wtf.. lol it was a tear in the coupler that's on the turbo.. my car kills couplers this is the second one that I blew a hole in.. dont know how it was still holding boost so well but I found it today Wen gapping my plugs. It was right by the clamp on the side closest to the firewall. Replaced it with a nice vibrant coupler and have had no problems as of a few hrs and wide open pulls..

 

Stamina I'm going to do that anyways.. what is that site? I've never heard of it..

 

And startingline, I don't have the intercepter.. I got an aem wideband for 20 bucks in the box.. lol shoulda sold it and got an interceptor but i didnt lol.. but the gauge is reading good though 12.3 wot so that's good.

 

Glad to hear you found the issue! If nothing else, you're better off with the plugs regapped now and know what to keep an eye on.

Many people think that just because they are making boost or normal boost levels that they have no vacuum leak. I had a Hahn IC blow a weld once and the turbo was still able to make the normal amount of boost. The problem was that it was doing it by spinning the heck out of itself, and it later led to a turbo bearing failure.

WOT-Tuning.com is Trifecta's new forum for trading stories, finding dealers, troubleshooting issues with Vince/dealers/other customers in realtime, uploading logs, downloading tunes, buying tunes, or finding reference information (like FAQs) in general. It's pretty much revolutionizing how Trifecta works now.

It just recently rolled out and is making Vince's job a whole lot more efficient and easier to manage. When you send your logs to Logs@WOT-Tuning.com, a support ticket will now be created, popping up on Vince's "dashboard" as something he needs to work on. It also allows you and Vince to keep tabs on the current status of how things are going with the customer's tuning process, the history of the tune/log/issue, and a level of organization. In the future, it will allow multiple people to be able to review and write tunes.

Ok man that's awsome thank you for the information I really appreciate it. Cuz I've been waiting on Vince answer my email reguarding my data logs since Aug or so of last yr no bs.. I was about to go with HP tuners because of it and get it pro tuned. Which is still Probly the best way to get good efficient power and drivability..
