Yes like someone said above you will at least need a map sensor. I also added the tuner to the Utec but thats not needed.


If I'm not overboosting I understand I wont need the WG spring?
If you not over boosting then great. I was so I had to change a few things to get them the way I wanted, safe.


I intend on a few gauges as well, but not sure which ones are necessary. I've posted many time about the turbonetics but its hard to find my old posts with so many different types of info.

My purchase is kind of in the works right now, and its happening very fast so I'm scurrying ot get everythign I need. Would $1500 be fair for install/tune for turbo + utec? Or am I being unrealistic?

Depends on where you go. IN saying that where were you planning on taking it?

You'd have to have the ecu reflashed for the 440cc injectors

I just happened to buy a utec today, and will drive to gtm in april to get it installed and tuned. Should i leave the stock 380s in and tune or upgrade to the aps 440s that gtm suggested, or maybe 550s?. George also said i would most likely need a fuel pressure booster as well, not to sure what that is.
TIA.

Forget 440's, waste of money IMO. Skip up to the 550's.

I came across this thread. Did original poster ever get the UTEC? I had no problems with the TN reflash...builtproof! But add a UTEC to a reflashed ECU and PROBLEMS. Curious where this setup is.
P.S. Reflashed stock ECU back to stock parameters and all is great.

You may wanna specify what you mean by "problems" because I have none as far as engine management goes with the TN reflash and UTEC combo.

Wow...that's interesting. Like I said I never had a bit of issue with the TN reflash, everything was spot on. When I wanted to up the power so I put in the UTEC, I had tons of stutters. If I transistioned from the ECU to the UTEC slowly/ smoothly not normally any problems. But when racing (1/4 mile) it was a mess. I fought with it for 6 months or more. I came across a Ttuner that said I had the 2 fighting each other. He gave logical reasoning enough that I (terrified) had a stock reflash.
Problems gone. I know people with non reflashes and F.I. with no issues and of course the same of NA with UTEC and no issues. Myself and a friend who has a reflash, utec and twin turbo's has the same issues I did. I am sure it's an issues, have no idea why it doesn't effect you guys. The 1st tuner I had trying to fix is a tuner recommended my Turbo XS so it was not the tuner. The 2nd tuner just has come accross this problem before. I really am not looking for a debate just wish I had someone able to tell me months ago... sorry for the hi-jack.

I dont see how the two could be "fighting each other" as he put it, as it functions exactly the same as the stock ECU. Oh well.

The stock ECU is looking for and adjusting for boost...now you have 2. Just keep it in mind if you have strange issues. Keep in mind I am COMPLETELY happy now!

No it doesn't. The factory ECU is totally blind to boost. All the stock ECU does is adjust the fuel mixture and timing based on RPM/AFR/fuel/knock.

I'll ask him to give me an explanation in an email. I am not a tuner, but I know what fixed my nightmare- a reflash. There was obviously nothing wrong with my TN reflash...It was GREAT! The UTEC seemed so the problem I had it replaced after the 1st tune attempt. Nothing changed. I may have even burned a bridge with a great tuner here local because he was unable to fix problem even though he could data log it. Anyway when I see someone writing something similar problem to mine, I will share my experiance. That is not this situation with this thread....sorry.

This thread is pretty much done anyway. I'm not saying it's impossible for it to be the source of the issue. Reports of it just seem to be random at best.
