You can raise redline to 7K in tuneECU already.
The tuner bull is talking about is the real deal, he knows his ****, if he says he can get the same results without PC-V as with, then on that particular setup the PC-V isn’t required.
The ignition module has only really one use on a stock motor no power adder bike, ignition cut for the quick shifter, besides that you’re better off using the ignition tables in TuneECU.
For a force induced or nitrous bike, in my opinion the ignition module is **** near mandatory!!
