And this is coming from someone who is racing at the track monthly in a BMW M3.

Well all of my issues were def not from track use . The thermal ones I'll give you that , but since I've upgraded to the 525 it's been almost all wrong parts .

I just don't want him to think that most can't run an off the shelf 525 kit without issue. Issues don't come from driving it normally or spirited on the streets. Its a lot of power for daily driving.

Not to disregard what you have done for us in any way. We appreciate it.

Sorry to go off topic, but I meant 'trouble-free' in the sense of getting the correct parts. For me to have to source out 50% new parts after just spending $10K++ on the system seems ridiculous and a pain in the a$$

This guy right here understand my point of view.
If you are paying this kind of money, you shouldn't have to buy stress pills and take anger management courses.

I think all FI companies producing kits for the Z4M have issues in this respect. G-Power originally shipped the wrong oil cooler, and they were slow to send the tune.

Your best bet is to buy and install the kit at the same shop. That's what I did, and it's the only way I'll go from here on out. The customer is no longer the middle man, and the shop is on the hook to make the car right. PSI hooked me up on some free work after the tune was delayed, even though they had nothing to do with the delay. Made for a very happy customer and overall positive experience.
