IMO I think you will be happier with a complete kit, like the Radix from Magnacharger. After all the tuning, injectors, plumbing, blaa blaa blaa you could have purchased one! And remember, MagnaCharger offers a 3/36 Warranty like NO OTHER company.....That should say something about their product. + for street/strip fun there is no other!

 

I dont know where ATI got the 8PSI number from, but I have the 8lb pully and im making 12 PSI on this truck, So if you do go ATI, dont even bother trying to run the FMU, just get injectors and tuning in the beginning so you dont risk having a problem.

I dont know if its because i have a D1SC or maybe because i have more compression than the LQ4 motor, but Im making a lot more than ATI says
