Default Speed Density or MAF??

I was thinking about running speed density. I was wondering if this is worth it over running a MAF. I have HP tuners to tune the car so it would be free.

Tell us about your car.

SD is not free.

As a rule of thumb I only say ditch the MAF if it's giving you grief. It doesn't make much sense to me to just toss it arbitrarily.

I ported the hell out of my MAF. Then I tuned for SD with wideband. Then I tuned the MAF against SD. Then I finetuned the MAF with the wideband. This method has given me the most steady and consistant fueling.

Tha MAF is a restriction unless you decide to get a bigger one or porrt and tune the stocker.

speed density here, throttle response is so much better. just the way the car acts is so much better as well. i love it, if your going to spray leave the maf alone though.
