Before i purchase a turbo kit i know that the Ludespeed Stage 3 Turbo Kit comes with a Programmable Engine Management System. But im not so sure about the FAT Stage 3 kit. I went on there site and it only showed a brief description of their FAT Stage 3. Yes, i did a search and found out that Lude Stage 3 gives about 50hp+ and the FAT Stage 3 gives about 80-100+. FAT Stage 3 spools up quicker than the Lude Stage 3 kit. My questions are Does the FAT Stage 3 come with a Programmable Engine Management System? If not should i switch to the Lude Stage 3 or stick with the FAT Stage 3 and but the PEMS seperately? Do any of you guys have any of these kit? If so, would you guys tell me about them? I know both these kit are wonderful but still having a hard time choosing. Well i would appreciate the help. Thanks!
