Got mbc

I got my boost controller yesterday and I tested it out. I had to turn it down quite a bit. I wanted to see where it was so i went out and it shot up to 25 psi and held it for a good while before it started to come down. I thought the turbo would only do 20 psi tops. Well anyway after i let off the gas the battery light came on and i was just wondering why.

Holy shit our cars have battery lights? i never knew that.. anyways whats the setup on your car? like what turbo do u have and what mods have u done to it.

stock turbo
apex n1 exhaust
greddy types s bov
ngk spark plugs
10.4 spark plug wires
turboetics mbc
a/f
oil pressure gauge
boost gauge

Boosting over 15 or 16psi on the stock T25 is a waste of time and wear and tear on the turbo. At pressures higher than that, the turbo heats the air too much to create a power increase. So all you are doing is reducing the life of the turbo. As far as the battery light, I didn't even know we had one :lol:

You should really put that in your sig.
