M3/M4/M340i/M440i (G8x/G2x) Stand Alone AFS™

Great buyin experience!!

Both excellent quality and service! Alex was very helpful and a fast response , literally minutes !!!! Everything came in the boxes well organized and logically placed in every box…. Attention to detail is the key!! Good job guys and thanks for everything!!!

Can’t keep up with fast spooling turbos.

The fuel pump cannot keep up with my 6870. Tuner has to leave the pumps on in a separate map, not safe and will melt the harness. 525s would have been a better choice with check valves. Regret this purchase, need to find another solution. Real person not a bot.

Afs 745
