do i need to go sd or keep the maf?
do i need to go sd or keep the maf? i made this thread since either affects what intake/tb im going with. ok well i have a 383 ls1 10.5 compression probe pistons made about 451rwhp and 512rwtq. and i want to put about a 200 shot of nitrous. i heard the maf is crap at about 600fwhp is this true can i keep the maf. and with the sd tune does it need to get tweaked for the differant seasons?
and a question on the side when a tuner, tunes a motor for nitrous how does that work? since the motor is not running on nitrous all the time and its ussually 150 more for nitrous tuning.

Wet shot or dry. If it is wet then it will take care of itself. I hope you have wideband and some way to tune it. Like HPT or efi live. How will this effect what intake u are getting? If it is a wet shot then ur MAf will be fine. Dry will be a bit more fun. but can be done.

put the fogger in front of the air intake sensor. u can then see a temp difference when nitrous is on and off. ok then go to your timing tables. go to intake air temp timing adjustment. soo when it sees the cold temperature from the nitrous u can then set up how much timing u want to pull out and as long as u have a wet kit tune the fuel with the jets on the fogger.
The MAF is not crap. It is a device that is employed to measure airflow. The pcm "knows" or rather is told by software definition the displacement of the motor. The only variable left is how much airflow are you getting. Obvisouly, our Hot Rod quest for more power revolves around getting more airflow. The MAF does not have a HP limitation. The software running the MAF can only display/read ~500 grams of airflow. Typically vehicles making at or over 600rwhp are taking in more than 500g of airflow- this is where the misconception begins.
