      Is the chart factoring in stock turbos? Or is the chart just based on what the individual part is capable of?

    I think there might be a sweet (cost effective) spot at upgraded injectors, down pipe, stage 2 HPFP & hybrid turbo. Say US$6500 & stay within the safe limits of mani, trans & engine

    Hey kern looking to get some parts to get custom tuned. Would running pi doing a stage 3 lpfp and then a tu pump stock injectors be a decent setup? And would that be safe on stock turbo I plan on running that for 6 months or so till I go pure850 I think, will that setup work?

    If you run 93 octane but swap out for a 10.25:1 or 10:1 compression ratio would you still hit octane limits before fueling? I don’t have any E85 accessible to me and everyone says octane boosters do terrible things to your engine, idk what to do.

    • @kern417

      Yes but the limits will be higher. It's easier to just add meth injection

    When replacing Fuel injector do you have to reset the adaptation? or is it just a plug n play kind of deal.

      Stock are plug and play. Upgraded require custom settings in the tune.

    If I wanted to comfortably max out my stock transmission and engine reliably to daily drive on my gen2B58, that would mean around 650HP and 650lbft torque right Kern (or could I go higher torque with a custom transmission tune?)? The best and cheapest way too achieve this would be pure800 with an intake manifold that supports port injection correct? stock injectors and LPFP should be good with that if I'm running E50 right?

    • @kern417
      @kern417  Рік тому

      @@kern417 not gonna lie after doing hella research and watching ton of your videos I cancelled the PG intake manifold and decided to go with turbo/hpfp instead. Just can’t decide between the DAW flowmax or the new Vargas VTT GC-MID. Apparently the MID is made for TU engine and can support 650hp and is like $1k cheaper than DAW.
