Hey guys!

Recently finished an LQ4 swap on my 04 GTO and been attempting to dial in the tune over the past couple months. Tonight was the first time I've taken it out to run some WOT data logs and a Dragy hit and boy, was I disappointed. Felt just plain slow. 13.73 1/4 with a 12.55 60-130. Granted it blew the tires off through first, I would have expected a way faster 60-130.

Been combing through the logs and noticed that the airflow seemed way low for a H/C/I setup (BTR Stage 2, ported/milled 243's, FAST 92mm). Stayed around 35-40lb/min the whole WOT run. Timing seems fine, MAP was solid, kinda at a loss of where to look honestly. Attached the log if anyone wants to take a look.
