hi all, just took my evo 3 out with my mate when as soon as i came on boost i just herd lots of air but no boost, im not to concerned as i think its probaly a split boost hose as off boost its fine, and when i reved it up on the drive it was ok , cant look at it yet as the weather is shit, what do ya think ive done a quick check and all the hoses or on thats why i maybe think split hose or leaking oem d/v
