    So, last week I took my car to the drag strip for the first time and I ran a ridiculous good number for my first time and being in 93 octane only. I've looked at the log but other than my timing (IGN_1) dropping from 7 to 4 I don't see any other concern. The timing did recover, but I read...

    So I was looking into purchasing a jb4 and saw that there's 2 options the CARB approved one or the one with fuel control wires. I was just wondering what is the main difference in between these and also I live in Florida so I don't think there's any emissions here in Florida. But yeah I was just...

    So I been using 93 octane since start, and I been playing around with map 3. What should I use with a stock 3.0t non redsport. I’m enjoying map 3, but I don’t want to hurt my baby since I’m stocked. Here’s a pic

    My new q50 3.0t with jb4 my old genesis 2.0t stage 2

    Took this the day before I got rid of the genesis. I miss the car a lot, single turbo nosies and blow off valves, big back fires and 2 step, especially the manual. The love I have for my q 50 definitely out weighs that sadness. Man they look so good together wish I could of kept the genny as my...

    I live in a state where 93 Octane is readily available at almost every pump. A person I know with a Q60 says he is able to run 21 PSI on 93, but he has a fairly newer model, so I am not trusting his experience. Can someone who has put a few thousand miles on 93 tell me what your max SAFE PSI is...
