If stage 1 is used for example with hassans mods the scoop, intake, x pipe exhaust, with he puts stage 2 wat would gain be? Knowing stage 2 can be used with headers
This is why I said lets not get too hung up on the stages. Sal creates each tune with your mods in mind. If you dramatically change the car, you will likely need/want a retune to get the most out of it. There would likely be little difference between the stage 1 and stage 2 tunes with the same mods on the car as, like I said, the tune is tailored to the car's current mods.
The Tune for this group buy is good for about 20-30hp gain as shown by the dyno plots, each car is different hence the range...
Here's the big questiob,
Let's say I purchase a stage one tune, than I decided to gutt my cats and want a stage two tune, will i have to fork out another $1,000.00 for another wire?
Researched old posts and the retune for cats/headers from the GB tune is $150.00.

I think I'd need to do Stage 2 since i've got custom Sec1 & 2 with Eisenmann Race Sec3, RPi Scoops/Plates and the BMC panel filters.
My only questions when will this be official and how long after I send the money do I get my tune.
Do you still have Cats or are they changed from stock? Also I have cat heat delete (quiet cold start) on my RK Stage 2 Supercharged E39M5 and it's quite noticeable the difference...
This will be official when the lists gets to 15 confirmed purchases, so need to push your E60 buddies to jump on this so that all can benefit from the pricing! I'm verifying that this works on the E63 (pretty sure it does, just want to talk to Sal before I cross post), and if so I'll cross post over there to drive up some more folks!
