Hey guys, I just off loaded my 99 V-10 and moved up to a cummins. I have read a lot on this site that an EZ is the way to go for a first upgrade. I only have 250 miles on my 01. Is it too early to install an EZ and are they difficult to install? My EGT and boost guage should be here soon from Geno's ,to be able to keep an eye on vital signs. Thanks for any help!!! Jace
