Boost.. Not making 18 psi..

528 Views 2 Replies 1 Participant Last post by  Kevin Hornsby
Me and my friend installed a TurboXS MBC, a BCC, and a boost gauge last night.

I haven't had time to get enough road to stretch my legs but I am making about 16psi in third gear, should i be able to make 18 in 2nd and 3rd? Does the gear even matter how much boost I can make?

How come I am not making 18? Will it go higher than 18 besides spiking?

was it boosting at that level before? if so check your connections for leaks.
If you are checking boost after the ic it will be lower i check mine at the intake on the nipple pointing down at the driver tire just cut into with t adapter.. i get like 17 but its after the ic if before it will be higher.... hope that we checked this theory with 2 boost gauges.
