Default Need help with Speed Density Tune

I have made a major change to my car this year. I went from a Fast 90/90, 42# injectors, and SLP MAF to a Super Victor, 4150 Throttle Body, 50# injectors, and a speed denisty tune. Here are some of the questions I need help with:

1. What has to be done to convert the current tune to speed density?

2. What do I have to do to trick/disable the IAT sensor?

3. How do I adjust to compensate for the larger injectors?

I am using HP tuners and I have done alot of research on the HPtuners site and here. I am just a little lost with the tuning. Any help would be greatly appreciated.

Click on the help files in HPT, there is a step by step how to for converting to speed density and or 2 bar.

You do not want the IAT disabled or tricked, it's a wonderful tool.

For injectors you need to input data for injector flow rate, voltage offsets, minimum pulse width etc. You will have to learn how to do this by reading a lot or pay someone to do it for you.
