Yeah there sure does seem to be a lot of people running these and I haven't seen any problems yet, but it is a very new product, like less than a year old really. Tempting not to get one, it is on my mod list at this time. I can only make 11-12 pounds of boost here at just over a mile high, would love to get that back up to 14 psi. I can only get 91 octane pump gas here, don't know if 93 would be required then to run 14 psi? Isn't the recommended(or should I say minimum required) fuel at sea level for these cars 91 on the stock tune?
As far as needing a tune, there are a lot of people running these on the stock tune,and Steve at Ripatuned says you definitely do not need one to run it.
