what about people with DPs and upgraded ICs? Will this not work for them?
Hypnotized,
The bigger intercooler will work fine with our tuning. The tuning should respond very well to the increased airflow (aka power) gained by having a better intercooler. The time we spent to develop this tune and ensure that all air mass and torque calculations are correct at the higher power levels create a perfect platform for bolt-on mods. Because these cars use a Mass Airflow Sensor to measure the incoming air, any additional air will be accurately measured and the spark and fueling will be adjusted appropriately for the best, safe power we have already tuned for. Cooler intake air temps from the more efficient intercooler will also be measured by the boosted air temp sensor which will also correct the spark and fueling correctly. That part is no different than the correction made when the outside air temp changes.
Replacing the factory catalyst is typically not EPA and CARB certified authorized, so we would not typically test these types of components. In reality, as long as the replacement downpipe does not cause check engine lights due to poor O2 sensor readings, the Hypertech tuning should work fine.
We did test aftermarket exhaust systems with our tuning and found that they work just fine. The additional power provided by the exhaust system is immediately accounted for by the ECU, and because our tuning maintains an accurate engine model in the calibration, the gains are optimized with the addition of the exhaust system.
