Power dip
Hi everyone,
Iv just been looking at my dyno graph and am a little confused, there is a little dip at high rpm and then just before redline the power shoots up. the car has a 5th injector that is activated only at certain times and I think it is otherwise using stock injectors through a piggyback ECU. I was thinking that maybe the injectors can't cope and that's the reason for the dip and that the spike is from the 5th injector, please let me know what you think

A t3/t4 hybrid turbonetics turbo was used along with an evolution external wastegate, BOV, front mounted intercooler and all the usual plumbing, boost controller and engine management system, full stainless steel exhaust and centerforce clutch. At the moment the engine has done 30 000km after the turbo conversion and rebuild and is running at 0.9bar. It is the 1.6 by the way. The turbo seems to have a 58.2mm/75mm wheel in a .63 turbine housing.
