Re: My 181 install experience. Boost levels + concerns & thoughts

So I don't think injectors are too much of a concern, although that's been one of my main concerns. I'm installing methanol/water injection soon, which will ease that problem, if it exists.
I installed a boost gauge this weekend, and I'm running just over 20 psi max with the 190.5 pulley alone.
And no, I don't have my tune yet, either. I'm going to get the methanol/water injection installed, then get the tune to take into consideration all the mods I've made.
I'm interested in videos of SRT-6's with sound. From those I've heard, mine runs MUCH quieter, and I'm trying to get a sense of whether it's mine or the louder ones I've heard that are the anomaly?
How many miles have you been running the 190.5 pulley? Have you ever dyno'd to see what you air/fuel ratio is? Could the richness just be from everyday driving and you are actually running lean while hitting the 20 lbs of boost? That's where my concern is.
My exhaust is stock and I consider it to be very quite too. Was thinking of changing it but it's more fun to woop up on someone without all of the drama of screaming exhaust.
