it seems to me you have no idea how to tune it, and also you really really should get everything done right before you start hammering on it. so let me get this straight you have no clue what you fuel pressure is at and you have a boosted application, that is not the brightest thing i've ever heard. i bet it's running to rich and overloading the crap out of those stock 19 lbers, what type of fuel pump do you have in it? you are very lucky that you havent burnt a valve or put a hole in your piston. and your MAF being stock is waay undersized and with that 30lb C&L tube is messing with your computer. so get your fuel pressure set right, then get the right MAF in there with the correct metering tube and i'm pretty sure it will solve your problems.
