Most stage 2 tunes recommend cooler plug.
just curiosity and wanting to learn
why are plugs so much more important with tune? Do you go colder with them or something? And why changing them early?

Boby,
Tunes can be fun, but they can be costly. I personally wouldn't but since I don't track my GTI it already goes faster on the street than is wise to go. Just know that they can void much of your wtty B4 you tune.
That is awful to hear but you seem to understand the risks. I was about to go get ECU + TCU from Uni, now that i wet my pants i will think it over some more.
Best of luck going forward OP.
The big problem is that nobody really knows where the limits are. All we do know is that these cars are pretty reliable with regular maintenance and normal driving.My last foray with turbo cars was with a 1993 Mr2 turbo. These were great cars and we all were in the mod mode with them. I turned up the boost on the stock motor and quickly blew the #3 piston...car ran reasonably well even with the blown piston. Took the engine apart and found that the top ring lands in the #3 piston had shattered. They are very thin and not forged. Well, the cylinder walls were fine, so put in a new piston and rings and reinstalled the motor. It wasn't long before the same thing happened again. We took out the motor and installed a complete jdm long block, which has a bigger turbo and more aggressive tune...this was a beast! It lasted about 3 months before the same thing happened again. My friend had a 20,000$ race engine prepped for his mr2..made over 400 hp at the wheels...a real beast! Had completely forged internals...lasted about a year...this time the pistons held up, but the cylinder wall cracked...so I guess some are having the same problems with the gti...the engine is already tuned to the ragged edge in stock form and the components don't seem to hold up with too much modding. All it takes is one glitch in the engine management system ...one lean cylinder, and the damage is done...usually happens at low rpm in situation where it is not even streesed
