depending on all you have done, I've realized the stock subaru solenoid is absolute garbage. I was unable to go over 18psi and even 15psi in certain weather conditions. This is with a TD06H-20G of course, I replaced it with a GM BCS and have been able to hit 20+ with ease, under any weather conditions.

Probably cause you didn't have the brass restrictor and/or abc in line. Wrx hackers has alot of good info. Might wanna do some searches like "utec and links" or "utec and newbie" or "mick and guide" or something.

Yeah, I definatly had the restrictor in-line. Funny, because I got it to the point where I had upwards of "450" values for my boost settings and it would only do like 17.5psi, and not be stable in that at all.

My position stands, subaru boost control solenoid = sucks. delco solenoid was the best $40 I spent on my car lol

When you say full boost - what PSI value are you referring to? Stock value or a new value that you would like to hit?

Where to add fuel and take away fuel effectively really will require a wideband o2 sensor and display of some sort?

And Hippy is right, WRXhackers and this site seems to have the most info on UTEC.

Don't get too frustrated - tuning your car is not easy when your new to it. I would print out the manual and Mick the Ginges tuning guide and read the heck out of 'em. Then I would log several pulls and share them on this site with other more experienced tuners. Good Luck.

Read, read, read the manuals. Get the manual from Turbo XS and make sure you understand not only what to do but why you're doing it. In the sticky's for the UTEC forums there is a write-up by Mick the Ginge (PDX tuner) on how to tune using UTEC's in a step-by-step kind of fashion. Again. Read all of this and make sure you understand not only what you will do but why you will do it.

And like other's have said, make sure you have a wideband o2 sensor(buy or borrow). Trying to tune fuel without it is suicide. Once you have fuel tuned you can move on to boost and then timing.
