I have a Evoms GT610 kit on the car and I normally see boost of 1.2 bar with an occasional 1.3 bar spike on 93 octane (car was tuned at evoms for AZ 91 octane fuel) in summertime weather. I took the car out last weekend in 50* weather and i saw spikes up to 1.4 bar and it settled at 1.3 constant. I have a feeling that if I have the car out in any cooler weather, i may start seeing higher spikes and higher sustained. Is this something I should be worried about? Why aren't the wastegates opening more to bleed off the additional boost? It seems that the car should be at 1.2 bar regardless of weather conditions? I feel I have a little bit of a safety net since the car was originally tuned for 91 octane and we have 93 octane available here. Any suggestion or input?

Thanks in advance

 

your right.... but call Evoms and see what they say...
