boost loss thru intercooler

what kind of boost loss are you guys seeing with an a2a intercooler. with my 8# spring I was seeing about 7.5 # but with my added intercooler im seeing about 6.5 with the same spring and im reading it at the intake but opening the wastegate with reference at the turbo. is this good. car is running great feels the same power wise with less boost.

Around 2psi drop is pretty typical.

Remember a lot of that pressure drop is temperature reduction not restriction. Temp and Pressure being directly proportional.

yes I thought id loose some boost and the car feels great even at 6.5 psi . i'll get the afr dialed in then add my 2# spring and see how it runs . I think it feels good now due to the fact that it is not spinning as bad and has usable power.

I see 1.5 - 2 at higher boost levels (20+)

but its also dropping air temp over 100 Degrees.

I might add a port in the tube after the intercooler and reference it there that way I can run 4 different boost settings with just my 2 springs. or just buy a 20 dollar boost controller and forget about it. lol.
