[TTTurbo1.8T]

The hesitations could be your traction control stopping your tires from spinning if you punch it around corners, mine does that a lot but a little yellow light flashes on my tack thats a ! with a circle around it, all it's doing is killing your acceleration so that you don't lose traction, you'll notice it especially in heavy weather. The start up issue is sometimes the same with mine, I put some Heet in the gas tank and it's doing fine now, but if you don't have any in there then just rev it a little and it should be fine. You can't really compare a video of a turbo spooling to the actual thing, sound qualities are going to be vastly different especially if you were watching those videos on youtube or something like that where the vid's have very low quality. As far as the stock system goes, I wasn't too impressed either with mine, which is why I'm putting a new one in it in January. Also another thing that may help your problem with the power not being as noticeable before would be fill it up with 91-93 octane instead of 87 or 89, the difference is quite noticeable. With your car hesitating with cruise control on, that happens down hills, it has to slow down a bit to keep your speed consistent, if it's doing that on a straightaway I consider that something you may want to address, as far as using that warranty, don't think just do. Not using that would be like me saying Jessica Alba is going to be at my house for 10 more days...do you think I should have sex with her or not?
