Thank you for the suggestion . Fuel pump upgrade is next. Just out of curiosity, how much boost from your attached tune will produce? My current tune , can get around 130kPa of boost and the actual lambda is 0.8, fuel rail press 12400kpa. Is it still safe for the stock engine and turbo ?mituc wrote: ↑August 10th, 2020, 9:40 pmThe tune above will work for cars without upgraded fuel pump internals, however, the fact that you have a way better flowing exhaust some custom tuning of the wastegate duty cycle table is required.
Going with exhaust mods and no fuel pump internals and intercooler upgrades is not only useless (because you can make the same power on the stock turbo because the safe limits are below the max capabilities of the stock setup anyway) but also dangerous especially (but not limited to) gen2 3MPS/Mazdaspeed3. So I suggest to get pump upgrades last week and install them yesterday Any pump internals you want, not particularly in this order: Autotech, CorkSport, Cobb, VIS Motorsports.
Most of my flashed was to get rid of KR . Last time as high as 3 degree, pulled out some timing in the specific area, now KR around 0.05 to 0.5.
