Ok this ? has been going around for awhile now so bear with me, im a first time diesel owner and love it . I have sbc intake and sct livewire with rcd 450 street tune im not careing for it i had the gt tuner before liked it but it wasnt enough and also wanted dpf delete what is the difference between the spartan,and black maxx versus sct and what are the tunes they come with,im looking to get the most power without destroying my tranny untill i can do an upgrade on it..

 

well i would go with innovatives tunes with a sct touch srceen personally. if i had the chance i would do that. . i love these tunes better then any others. dont worry i was playing with fire and the dam thing didnt like it. you'll be just fine with your trans for now.

 

you can put any tune on it, just be sure the right foot isn't to the floor ha, you should be ok as long as you don't rod it everywhere, i would go with SCT though, you can get custom tunes and everything like that
