I am going to have my ecu (98 ecu) tuned in a couple months. I was wondering how hard is it for the tuner to convert it to Speed Density? What are the benifits of a Speed Densitiy tune? Should I get this? what do you guys think?

I am fine with keeping my MAF. I though I would inquire about the Speed Density tune.

I'd do a lot of reading if I were you. If you aren't comfortable with the concept of SD by the time you make the decision, just go with a MAF tune. Done properly, they should make the exact same power (as long as the MAF sensor isn't choking the airflow to the engine).

yeah & 98's make it just that much harder to tune in SD as it is.

SD is hype unless your car really needs it (usually higher psi turbo apps).

I read a little in that link that was provided. Thats what I was thinking. I do not think I need it in my 400rwhp car.

I tuned my 98 Trans Am in Speed Density mode and I'm a first time tuner. It's actually very easy with EFILive and a wideband O2 sensor, just do some reading beforehand.

people just thinks it sound fast, I mean Speed Density just sounds like a cool mod to spout out at the local car meets.
