I am one of the many happy customers with a Haltech, though. It is a very nice piece of gear.

I have a hot start issue with the UTEC. Its a pain in the *** in summer.
Have been wondering if the temperature compensation data was off.

I did the switch from the UTEC to the Haltech, and I cant honestly say Im happy at this point. My car hiccups twice as much on the Haltech as my UTEC did at the same boost levels. My Haltech also has a weird throttle issue where I will be driving casually and gun it, only to have the car not build boost and the revs not climb, the engine just stays at the same speed stuttering like my TB is failing. I have to let off the gas for seconds at a time to almost "reset" the throttle or something-that is what it feels like at least. I also have WOT hiccups that occur when gunning it starting from 5000rpm's or so. The most frustrating is the cruising A/F's that gradually get leaner and leaner eventually turning into sputtering and making me let off the gas then get back on it. I cant even set my cruise ciontrol the car hiccups like crazy.
This is the main reason why I havent really been driving my car at all this summer, it just hasnt been enjoyable and spending more $$$ at this time to make things right *again* doesnt seem like an option anymore. I did drive another Haltech on an almost identical setup that didnt experience so many issues. Maybe one day I'll have a car that runs the way it should.

Alberto I sent you a PM about your throttle issue.
I've been thinking about ditching the UTEC and going with something a little "better". I'm in the same boat as others though, it's hard to justify the price and time it will take to get it "right" when the UTEC, for the most part does an OK job now.
Does anyone know what used UTECs are going for these days???
Also, does the haltech have a boost controller built in? I need to get one since the UTEC boost controller is terrible at best (at least in my application). If the haltech has a built in boost controller that may be the motivation I need to make the switch!

The closed loop is configurable unlike the UTEC, so you can dial it in to work perfectly in the event of any overshoot etc. Also, with the Haltech plug+play reading in wheel speeds and percent wheel slip, you can setup your boost off of those. For example: wastegate in lower gears, ramping in more boost as you approach interstate speeds where you can hook.

I have a car PC, with a touchscreen, so this hasn't really bothered me - I know there's a 32 in/out module due out sometime. Not sure if the AIM display can control boost...
Another alternative is to have your max PSI based on throttle position...

I've never run the UTEC, but I can tell you that my Haltech setup runs just as good as the stock ECU did. Hal is definitely a wizard with this thing. I'm running 600cc injectors...and I tell ya what, It starts on the first try every time...no matter if it's hot or cold...and I NEVER have to blip the throttle. Clutch in, and start. From what i've read of the UTEC, I'm so glad I spent the extra money and went with it. Plus, with the customer support that Hal provides...you are never more than a phone call away from all the support you need!!!

So it has speed dependent boost control!!! One of my plan is to get an EBC like the EVC6 so I can set my boost on each gear. If the this feature actually works then chit, I might as well sell my Utec and upgrade to Haltech. Does Haltech has it's own BCS or we can use the one from Turboxs?
