Hi everybody. i been tuning on the dodge viper acr and got mine running a 8.94. i know still needs work lol.my brother in law has the same car and couldnt get his past a 9.11.i gave him my tune and still no lower than a 9.08 even when i drove it. both fully upgraded and broke in, oil changed etc. why with the same tune are they so far apart on time.any advice would be greatly appreciated as we are kinda newer at doing the drags. we got our gtr's running even 8.97's but the vipers wont run anywhere close to each other.....
