They each have their pros and cons. Piggies have maps that can reconfigure the tune, flashes can be custom tuned to the engine and mods. Dinan is expensive but retains warranty. ECU flashes are not as easily reversed.

The flash would be a cleaner solution. That being said if you go with a reliable tune(JB4,AFE) you will be very happy with the results.

I am wondering about the new MkVII GTI as that EA888 engine with its new "larger turbo" looks interesting, BUT will it hold. I guess the first steering recall on this GTI has already set the VW trend?

ECU tuning has its pitfalls, coming from the MK6 GTI world, the North American ECUs had to be physically cracked open and bench flashed. If they weren't sealed properly water could get in and fry the boards. Piggy backing is how I've tuned my Diesel truck, through Banks, and my BMW with JB4, haven't had an issue with either.

First off, to all saying APR or a tuned VAG is unreliable, I ran my STG2 GTi for 80k and no problems, and no I don't baby my cars. APR is kinda-of the Dinan of the VAG world, they take their time; produce a safe, lower power, product than competitors. All that being said, has anyone ever contacted APR about entering the BMW world? They have the resources to...

Would be interesting if they did though. I would consider them as well. |

I absolutely loved my 1.8t Jetta with APR, served me very well for five years of family use and auto-x without a single issue. Had all the programs, full TBE and other goodies. I'd love it if they entered the BMW arena.

The Mk7 Golf R should be an interesting car. Fully disabled ESP from the factory, and APR should be able to come up with very good numbers. It's a shame their 4Motion AWD is FWD-biased. |

A buddy of mine has a tuned R32 that's a blast to drive but I think he has as much $ in --engine, suspension, turbo--as it cost to buy. I drove a tuned Mk 6 about a few months ago, appeared to be a piggyback upgrade and it was wicked fast. Was thinking a similar upgrade would be just the ticket for those very special occasions when I can let my hair down, so to speak. And, from what I read, they're undetectable (?) from a warranty perspective which sounds good. Otherwise I've already got more performance than I can use on the street (and I love to use it!)... 228i, to me at least with the M package is such a balanced machine, fits like a glove, and is so responsive I didn't need to test the M235 which I'm sure is great. But I've had high(er) horsepower rides in the past so have been there done that. Keep posting the tech details and pros/cons, guys--this is great to study up on!

MK6 GTI motor can easily handle the extra power, what I'm suggesting is that the rest of the car isn't.. Specifically cooling system, brakes and clutch
Those are known unreliable areas if these cars even at stock power levels |

BMW aftermarket is usually more or just as expensive as APR. I wouldn't see why they wouldn't make any money on BMW products. I think their focus is more on VAG products and that's it. They probably don't want to take on any more work then they do right now as I'm sure they're plenty busy. My .02 though. Also, I'm considering Dinan and not primarily because of the warranty either. |

I guess you could say that though. Some people as myself will not consider a jb4 as an option. |

Endusers need to bug GIAC more...maybe they will finally release their N55 tune to the public.

Both APR and GIAC take their time on R&D, they double and triple check on a dyno and real world and sometimes on the track(I know GIAC is tested on the track as we lots of testing for them on the BMW platforms) to make sure the software is reliable, smooth and deliver power within the designed parameters of the hardware. Piggy backs are just not reliable enough for track duty. I can't remember the last time I see any piggy backs ran reliably for the full 20-25 minute track session. Often they are in the pits resetting or the vehicle will go into a limp mode in a couple of hot laps. |

Yup you're right. The MK7 doesn't have a bosch ecu anymore that's why. It's a Continental SIMOS 12.... |
