I've said this before, and no doubt I'll say it again.

For the most part, the price of the EMS doesn't matter. What matters is the tuner you are going to use. Find the local tuner that you are going to use, tell them what kind of features you want, and buy what they suggest. You'll be FAR better off using a unit they are familiar with, it'll save you bigtime in tuning fees, and it will give you a far better chance of getting everything set up correctly the first time.

John Reed is in an expert in lots of EMS.s

so then it becomes a matter of YOUR budget.

Ie...MoTeC SYSTEM will easily climb into the $8,000 range (MoTeC 820+M820 Harness + CDI-8+CDI-8 harness plus tuning). Flex fuel will add a bit more but John reed is one of the Pioneers in the E85. Yes PRIOR to Pro-EFI coming out. ;)
