Your best bet would be to ask BMS directly. If it's doable and safe, logs will show.

You wouldn't need stage 1 if you ordered stage 2.

There is an upgrade price if you already have stage 1, but you can buy stage 2 outright...you don't need stage 1 to get stage 2, it's a replacement

Just bought my stage 2, I also opted for the laptop USB cable and the flex fuel E85 wires so I can run a 50/50 mix of E85/91oct.

Can't wait to get it!!

I already got hesitation problem during acceleration on half pedal my mods are stg 1, afe filter and scoop I use ron92 I don't know if it's the tune or what. I did some clean but the problem seems to exist, I contacted bms and he said to remove the blue wire for solenoid and it did make a difference for few hrs then prob. back again maybe a vacuum leak.

I doubted it's the MAF, I took MAF from f10 28i same engine of course and bam no hesitation but the car doesn't feel it's tuned sorry I couldn't take any video before. so that means my MAF sensor is bad ? or it just needs to be cleaned

No one on the forums is going to be able to help you. If you have a check engine light then step 1 is to read that code using a BT scanner or JB4 (stage2). That should put you on the right path to finding the issue. A common problem is oil from those AFE filters is too much filter oil coating the MAF so I would not be surprised if its related.

It's dry filter not oiled, for the check engine light it disappears right after I shut the engine and if stage 2 should help then I will try it but it will take some time because I have to send it here.. I did some injection clean and it helped but someone told me the tank is filled with residues because fuel here is very bad and there is no ron95 except in some far places, so I will try to clean the tank and the whole fuel system and will tell you the results. thanks again
