I've said it once, I'll say it again, that thing should be pulling strong a bit past 5k rpm...I'm still SD and am completely stock(stock HO) from throttle body to oil pan with nothing more than exhaust and my car pulls stong up to 5200 in first and second(even more so when I had those header mount glasspacks on). If you're dumping the clutch when you launch, that could be part of your bogging problem...it needs just a LITTLE slip.
You've got plenty of airflow in with that GT-40 intake, CAI, MAF conversion...and plenty of airflow out with your exhaust set-up....check your timing?
Good luck man!
