I was driving down a back road this morning to road test the MSD Stacker.
At WOT and about 5500 (in 3rd gear) a loud sound is heard from underhood and the power hits a plateau. It almost felt like it would not rev any higher but I was running out of road too soon to know. Boost peaked at 13.2 pounds in 65 degree weather.
It's an odd sound, like a whoopie cushion or really loud radio static. Perhaps it is a blow-off valve? Bypass? Severe missing? Belt slip?
I have a 2.93 upper and stock idlers. The belt has about 15k miles on it.
Any ideas?
