Posted this in the motor problems section and didn't get any hits, maybe someone can help me here
Normal boost numbers for me with the 275 and delete are about 15 to 19 at 80 mph. Yesterday I noticed that the whooshing sound I usually get when the torque converter locks up was not nearly as loud as usual and now my boost is only about 7 to 9 at 75 or 80 mph. Anyone know what could be going on? I haven't lost any coolant and just a quick visual noticed nothing out of the ordinary. I still can see 25 or 30 psi taking off without going WOT although I have seen 55 or so in the past.
