thanks a lot bro, is there any good ecu for reasonable price except emanage blue?A TDo4 is pulling a lot more air into the engine, so long as the fuel is there to support the extra air you will make more power.
The risk is always there unfortunately. There are plenty of variables at work.
When installing a P&P ECU take all the necessary precautions. Monitor boost levels, air/fuel ratios, apply some sort of knock detection, start at a low boost level and work up, etc etc.
In my experience 9/10 times it will be fine, but there is always that one time when it isn't!
