Default I dont know whats wrong now.....piston ring?

ok so my car has been running great the past couple of months and i just changed the oil 2 days ago...

its a 1997 audi a4 1.8t quattro with a stage 1 apr tune testpipe and exhaust

so i was driving last night pulled into my neighborhood and floored it... and it kind of gave out, once again im running 17 pounds of boost...so im thinking maybe a piston ring? does that sound right?

i havent driven it since but when this happened i put it in second and took it easy, no problems

also i want to add that sometimes on startup it blows some smoke and smells like its burning oil.

i neeeeeed the car for work tomorrow night so i would appreciate anyone that knows anything!!!!!

thanks

What color is the smoke? blue or white?

Grab a compression tester and run a compression test. How many miles are on the car? If a piston ring failed then there is no way you're going to have the car fixed by tomorrow night, but I REALLY doubt that's what happened.

Turbo oil seal. No or little boost needed when you take it easy, she's fine. Start pressurizing, thar she blows......

What Lyman says makes sense and I'd buy that. Definitely worth doing a compression check and also an ECU scan too though (never know if something is in there that didn't trip a CEL). If you find a cylinder with low compression, add a teaspoon of oil to that cylinder and redo the compression test. If the number rises significantly it's a ring problem. As stated above though, that's probably not that likely.

turbo is probably more likely given the loss of power mainly under load, though rings can still be a possible problem.

white smoke is coolant. Your turbo is toast or your headgasket is leaking....
