Simon Kribstock Posted May 14, 2019 Report Share Posted May 14, 2019 What does compressor surge look like on a data log graph? At about 7000rpm, my MGP/MAP spikes, fuel leans slightly (despite adding fuel) and power falls off. No knock or fuel/ign cut. Turbo is a VF48 with a billet compressor wheel.
