That’s the think this is the 2nd major repair I’ve needed for my GTIs...my mk6 has a bent rod. This time hole in piston. Nothing crazy I was APR stage 2 downpipe intake and that’s it. Just my luck I guess :/

No worries man as I’m curious as well. For comparison it makes a bit more sense. Myself alone I probably double the weight of my car lmao ?

Your tune is uber conservative. Look at the 6MT trap differences for stack versus straight file. Now that you have a built motor, time to send it
The closest APR car (no stack) in 6mt to mine is 7mph slower. That is a massive difference.
Haha I know...I’m not wanting to do meth but am curious how ethanol works or how people get more out of using a blend/ mix fuel.

Not very familiar with meth set ups. How does this affect daily driving? This is my only car and obviously my daily.

Yea I don’t think he was too happy. I was surprised from the outcome to be honest. He just dynoed this past week at 414whp and that night he ran another Caliber srt4 with stock turbo and tune with the basic bolt ons that kept up with him pretty well. So I’m wondering if his tuner fucked something up.
For the record, I went 123mph with no meth and E15.
Not needed (but it helps). I'm not going to shit on people who want to run it, but to me it is an extra wheel in the cog for minimal gains over proper fueling and E85.From a strictly power perspective, VP C85 at 40% concentration made only 4 or 5 less WHP than VP C85 @ 40%+meth. Average power with just E40 was actually higher. The results are within the range of error anyways. It is a negligible difference.

A good quality ethanol blend will unleash the beast. It's more a matter of finding a fueling system to keep up.

But if I go out of town and have trouble finding E85 I'm stranded. If I run out of juice on W/M I only need to not bury the throttle until I mix somemore. But you are right that its another part to fail, so it really is about picking your poison.For the record, I went 123mph with no meth and E15.

I'd rather go the W/M route because E85 is still a little sparse here in VA, sparse enough that I would have to plan stops on longer trips. Some states don't even have E85 available. If the GTI wasn't my DD, then E85 would be on the table, but then again if it wasn't my DD why wouldn't I have something else that doesn't need to be so economical? To me GTIs are cars that'd do work (loaded mine up with shit load of dirt/mulch the other day) when needed, get good gas mileage when needed, but also throw down with sports cars when called upon. Not many cars can do all three as well as the GTI.
Edit: Also, isn't the stoichiometric value of E85 under 10? Which also means fuel economy would take a good hit, which wouldn't be the case on W/M.
I heard a few people tell me meth will put holes in your pistons or simply burn them out and i know you weren't running meth, but makes me wonder if its true lol from my understanding the car is running cooler with meth, but maybe its the AFR that changes and causes it to fail.
Yea his tuner sucks if he's put loads of money into the car and a pretty much stock srt kept up. Also you should post pictures of your car, curious how it looks
Nah, a properly setup meth injection system will only make your car run cooler.

How many miles did u have when u popped the motor and how long was it tuned for?

I had ~44k miles when I got a hole in my piston. I have been stage 2 with downpipe/intake since about 25k miles.
