since i got my new exhaust my car is loving it we had a warm day today compared to what it has been and i was spiking at 16psi and holding 15psi what caused it to jump up another pound(im not complaining just wondering if exhaust can cause higher boost pressure)
thanks

 

She's a tricky beast. When its cold, boost goes down and the pull gear changes, but when its hot, boost is crazy and 2nd is outta sight!
