Mcx 260 kit Apex poping when boosts up ?? Help plz

[turbovector3]

It was running well for 5400km and I don't have any boost leaks but I think it could be some thing the matter with the computer not reading the amount of boost to start the second set of injectors on the mcx 260kit so it could likly be a lean pop it's not my rev limiter . That or maybe weak fuel pump
Thanks if you can help or if you have had this problem .
Thanks alot

I had this problem last winter. It was the boost line going to the mcx box it had been blown off by the pressure as I had forgot to put a zip tie on it.
Sled ran fine until trying to make boost then it popped and sputtered.
If its not disconnected it could have a hole worn through some where on that line.
Hope this helps.

Ok well great thank you very much I have figured it was some thing to do with that line or the mcx box but the line never blew off I had checked that out riding . But I asked around and I have a way to test if the second set of injectors are working
Thank you very much

check the other end of that line, see if its on or cracked. also pull the line off while riding it, see if popping gets worse
