hi all,
Aftre modification how reliable is the 996TT ? any if you guys have over 550HP modifications do you have any problems ? cultch ? gear noise ? burning more oil? let me know your feedbacks and your experiance with the modifying 996TT

I have gone one year with EVO/GIAC's stage 4 (600HP-ish) upgrade with a Sachs level 2 clutch (my mechanic felt slippage with the stock clutch so we upgraded pronto), I shorted one MAF the first week driving it after the upgrade last spring, but the replacement Bosch part held and the car cranked all summer. There was a slight uptick in oil consumption at first (expected and not a sign of engine "damage"), but otherwise the car put on thousands of miles in spirited driving without fault.
I just got my car back from the mechanic this week with its GT700 upgrade, and the car rips, using a Sachs level 3 clutch on the X73 suspension. I'll try the 100 octane program next week (with GIAC flashloader and 100 octane refill) once the rain cleans the roads of salt this weekend-it's been a LONG winter around these parts.
But last week the car ran flawlessly.
My most important recommendation would be to tune with a combination of mods. that covers the mechanical needs of a tuned up 996TT, but the most important factor is the presence of a local mechanic capable of servicing such a car, or prepare to ship yours away periodically.
