i'm new to tuneing but how to just going over to speed density help you pick up more power, cause when i take mine to get tunded, and converting isn't hard i'd prolly do the same

because the maf is only 78mm in diameter, and is a decent restriction when your flowing that much air. just take off the maf and put a coupler straight from your lid to your throttle body. should pick up a decent amount for a bigger cubed motor IMO. tuner will just tune in speed density mode.

if your maf isnt pluged in or doesnt work, your car goes into speed density mode

Speed Density won't net you more peak RWHP than a properly tuned closed loop engine. It can improve drivability with larger cams.

why not when your going from a 78mm opening with some restriction, to a free flowing 90mm opening.

thats like saying a stock throttle body will make just as much power as a 90mm
