Kent,
couple things you need to know:
#1 sensitivity of Turbo (how big and how easy are the boost spikes)
#2 IQ settings
#3 fuel type
#4 driving styles
For #1 you need a boost gauge - and this would be considered a "performance" mod and shouldn't be done without a boost gauge. If the turbo is extremely sensitive you could be at greater risk.
For #2, the IQ settings, this is read in the adaptation area, lower numbers = more fuel and the position of this could be very important in determining if you want to move the adaptations. Rule of thumb: the more fuel you add the more power you make and the more dangerous advancing with adaptations becomes. IE injectors = more fuel, Chip = more fuel, Tuning Box = more fuel - add in combination and you can have problems. Some of these fuel additions can be augmented or dimished by adjusting the IQ, but changing the IQ can require the special 3 sided socket the metalnerd had for sale.
Now on #3 (fuel type) ignition delay is what is important. Those New Englanders with their low Cetane fuel need more advance relative to the Californians and their High Cetane ULSD stuff they can get. BioDiesel also affects this. BioD effectively retards the ignition delay from my experience (YMMV). So if you set it up for low cetane fuel and suddenly give it some powerful stuff like that 50 cetane Getty in Tyson's Corner Virginia . . . WATCHOUT. This isn't something you want to be fiddling with after you fuel the car
And last #4. Driving styles. How you drive the car and the type of commute you do will impact the engine's longevity with the mod. You could be at the limit or in the danger zone but spend 99% of the driving time at steady state cruise control and as long as you always monitored the throttle and the boost and kept the peak power down (and fueling down) you won't be in any danger.
As GoFaster has said many a times - all the cars have a nice convienient power regulator: your right foot - if you don't use the power you are fine. WOT at all times isn't great but it is worse around 2,000 for the engine.
Yeah this all should be said in the previous many threads on timing adaptation, but this isn't a bad place to put it. So if you can determine what the Upsolute advance then that would help you decide what to do. You can always try it, but if you blow, you fix
