I say piece together your own kit
vortech tuner kit 2500
42lb injectors 325
Lmaf 100
jms sct chip 250
svt focus fp 90
afm powerpipe 250
---------------------
3515
For a nice little kit you need to dyno tune anyway.
For 450 more I could put a nice intercooler kit on there too.
so for 3965 you have a nice intercooled system and see over 400 rwhp.
