[QUOTE="01yellercobra, post: 16628037, member: 35549"] IMO speed density is fine if you're driving within a certain area. If you start dealing with altitude changes and different weather you have to tweak the tune for those areas. I drive my car to Az and Vegas and there's enough change it causes some funkiness in the tune. I could figure it out and tweak the tune, but generally if I'm in those areas the last place I want to be is in front of my computer. The MAF takes care of all of that. The car actually ran better with the MAF in the start up tune than it did with all the tweaks I had done with the speed density. Just find an unscaled MAF curve for your current MAF and populate the table in TunerStudio. Then use VE Analyzer to tweak VE1 and it'll come in quick. I saw where one guy made an Excel spread sheet that too the VE1 numbers and converted it to a correction for the MAF curve, but that's way over my head. You have to lock the timing and check it to make sure the phasing is correct. Basically you lock the timing at 10 degrees and there's an adjustment you make in the software to make sure it lines up with the 10 degree mark on the balancer. I'm pretty sure my setting is different than Josh's ([USER=11142]@GodStang[/USER]) so that shows you that each set up is different. [/QUOTE]
