Description
Extreme Power House is proud to offer you the best value combo deal for your BMW N55 F chassis 228 328 & 428!
We start with Bootmod3 (BM3) flash tune. The tune will increase boost, adjust timing, AFR and several other parameters to provide maximum HP increase while keeping stock reliability. Other BM3 features include on the fly burble tune, GTS roar, valve control and torque adjustment.
Adding power while keeping stock intercooler would be a waste of time as intake air temperature will rapidly increase which forces the ECU of your BMW to decrease power to protect your engine. Upgrading to the ARM Motorsports Intercooler ensures that temperature is always under control allowing your car to produce maximum power while keeping all the other components safe.
The extra boost added by your Bootmod3 will crack the OE plastic charge pipe and cause a boost leak.
Please note: bootmod3 will not work on your vehicle if your DME is locked. Order cancellations due to the vehicle's DME being locked will be subject to a 5% nonrefundable merchant fee.
