Another New Z Owner With Questions

[Jah_Happy]

my money is on heat soak - it’s a problem with turbos…

Especially with our pathetic oem heat exchanger on the non nismos lol. Every tuner / shop I talk to says to make it your first mod.

My JB4 tuner on Map3 demands 93 Octane gas ?

Is that true - I take the Q's with the Redline motor and mods to Gapplebees (that is from a roll usually 60-70mph and go) and I'm stock. This is one of the things I'm very curious about. I honestly don't expect it to be as fast/quick as the Cat, but if it is I will be pleasently suprised! FYI the Cat is still pulling like a train at 160
