[QUOTE="na svt, post: 13354969, member: 35346"] Here's the deal, a CR of 9.5-10.5:1 will work. The higher the CR the lower the max boost. Also, some tuners don't like to tune higher CR, FI combos that run pump gas, especially when it's less than 93 Octane. With that, I have no problem with flat tops and FI as long as the boost is kept to a minimum. The higher CR will allow for more pre-boost power and more tq. Do not go with a CR lower than 9.5:1 as it kills power. [/QUOTE]
