Hello folks,

I am writing this to ask anyone who would be interested in a GroupBuy for a Piggyback/Tune for their X3. 2011+ 35i or 2013+ 28i (N20) engine. After the poll votes I will take the majority and the one with 5-10+ votes wins. I am eventually going to try out more than 1 of these.

The options in my list are/only these as they're easy to install and remove, no need for power/ground/canbus etc. You can view more information on the below links as well.

- aFe Scorcher

If you guys want to get confused like me look at the N20 Dyno chart and this Stage1 vs Stage2 chart

I thought about VRTuned by VividRacing.com but I can;t seem to understand their warranty/policy nor is it clear on the VRTuned Tuning Box.

Please vote if you're interested, review the links above.

Ok guys got some contacts in the F15 forum and was able to get their group buy discount
Too many reasons to get the RaceChip Ultimate for a great price.

My friend will be getting the AFE Scorcher on his 535 and another one on his N20 car
