Ordering JB4 for M5 Comp - Any Georgia Installers?

At first was dead set on Noelle for its warrantee HP claim, but something seemed fishy after speaking with them. I was intrigued by the YouTube video review by "TheSmokingTire," and thought Noelle was worth pursuing. Oh well.

Its down to JB4 or Racechip but I have 93 and 100 octane avail to me so Im leaning toward JB4. I don't want to deal with the install so was wondering if there was any installers in GA / Alpharetta or surrounding area?


Thanks

why not dme tuning if you were considering Noelle?

racechip is like 2 connections in m5c. would take you longer to zip tie the box under the hood than plugging in the 2 connections

Noelles flash supposedly didn't void warranty and undetectable to BMW dealers. Who knows.

DME guaranteed detectable and will void warranty no?

I think for the people that are worried about warranty, you should not modify anything at all. As far as any tune being undetectable, I dont buy it. If you tune in any way and shit goes wrong, good luck.

any flashing is detectable. even Piggys can be detected based on the ecu storing boost levels and all that.

chances are low you will get burned with a stage 1 as far as it causing problems but a racechip or jb4 does not solve the problem of being invisible.

Don't worry about the haters, deep down they know that once you pull the JB4 out BMW cannot claim anything like they can with a flash tune. Flash tunes can be detected and anyone saying they are undetectable are con artists preying on retards. The JB4 is an interceptor so the DME does not see higher boost levels, even if a higher boost level is stored but the JB4 is not installed once the car gets to the dealer they cannot prove beyond a doubt that it was in there so they pay the claim if there is one.
