Normal boost for a non flashed car?
Noob question, I searched, but did not find the answer.
2003 996TT, 35K miles, bone stock. At WOT in 3rd/4th I am seeing .6 Bar. A friend who just sold his 996TT said I should see .8 or .9, thoughts?
At 11 years old, is it time to go through hoses and look for a leak/or serial replacement? Does someone sell a fairly comprehensive hose "kit"?
TIA

The DME attempts to meet the torque demand desired by the the driver and signaled by the e-gas system. If it can do this with in this case 0.6 bar boost that's all you'll see.
In some cases you will see 0.7 bar boost and in some special case -- at higher elevations is my experience -- even higher levels of boost: 0.8 bar, even 0.9 bar; with a stock but in good tune 996 Turbo.
Unless you have signs of a boost leak -- and so far based on what you've posted you don't -- you do not have to bother with the hoses. The hoses on my 03 Turbo are original and are just fine. Techs tell me they are normally quite long lived. Most often when they leak is it because they were removed for some reason -- plugs maybe -- and re-installed incorrectly.
Be sure the plugs are ok. They are due to be changed at rather low miles compared to other cars. They are also due to be changed on time too. Be sure you use high quality gasoline of the right octane grade and buy from a busy station. Do not overfill the engine with oil. How's the engine air filter? If original it should be replaced. Oklahoma (and Kansas and other states in that general region) can have high amounts of particulate matter in the air. (Drive through say Kansas in the fall when everyone it seems is either plowing dry fields, burning off ground cover, or burning piles of brush and you would think you are driving through a post-apocalypse zombie land. The air is so thick with smoke and dust particles you can cut it with a knife.)

Thanks Mac, I appreciate the reinforcement. Plugs are fairly recent, last 5K miles. Filter is new 2K ago. Biggest issue we have is crapola gas. We are pretty limited to 91 octane here in OK. I do try and buy from the same 2-3 stations which are busy ones. I have 6 cars that require premium, I hate the 91, but know about using stations that will turn their storage tanks on a regular basis. Engine oil is good, per the auto-check. I do wish I could check a dipstick-LOL!
If it ain't broke don't fix it!

Read your owner's manual. It's stated in there that if you must run gas with octane lower than 91,you can do so on a short basis and the computer will retard timing based on knock sensor input. In plain English,it won't run as good but it'll be ok for a short time.

like ppl mentioned.....6 to .7 that's only part of the story though
these cars are old even with low mileage. You really need to do a boost leak test. You'd be amazed at how many areas you can have a boost leak even on a stock car. It makes a huge different if you have a leak or not.

I can get 93, but, it's only available at two stations in the entire OKC metro area (million + people). It's about twice the price of 91. I do go there to get 93 for my Testarossa, and have on occasion for the TT, but it's quite out of the way. 91 is the norm, the big deal here is whether it's 100% gas or e10. A number of stations offer both.
I can also check for boost leaks, we have to occasionally do it with our Subaru's. I assume there are a few threads on checking for leaks?
