Yes, LS1s have a MAP sensor and you can run speed density. It is better to use one of the custom operating systems because you can use dual spark tables (low and high octane). And the EFILive COS's have other nice features you may want as well... As long as the PCM is a 99 or newer, you can us an EFILive COS. Hope that helps...

Yes u can delete any codes u want. You can unplug ur MAF and it will work. this can all be done with hp tuners. When you unplug your MAF it will use you low octane spark table and your secondary VE table. those will be the tables that you use now for all your a.f and spark changes. also your PE table will not be used anymore... Everything is done in your VE table for fuel
