Big jolt when I let off the gas at high RPM.
New 04 evo 8. Pretty much completely stock. Really smooth car -has 50k miles. When im going fast and I let off the gas all of a sudden, the car jolts pretty hard. Seems like my friends old wrx was the same way. What do u guys thing? I assume thats what happens when a whole lot of torque is suddenly removed.
Is this ok?
btw, anyone want to buy a skateboard? I need gas money =)

check the ic piping for leaks?
Anyone have a diagram or any usefule info (pictures) of the stock diverter valve so I know what Im looking at? I hear some people talking about reversed bovs but this definately has a diverter valve. Can that be put on backwards? I dont hear the sound of dumping to atmosphere so i assume it is only equipped iwth the stock div valve.

Yeah, its just the evo. I have a stock (+bolt ons and a tune, see sig). If i get around 14-18 psi and then drop to like 20% throttle (about 10 mm hg vac) the DV will open and there will be a 'surge' or 'buck'. Its even worse now that i tightened the stock DV spring to keep it from leaking (you'd be surprised how much air i was loosing thru that pos). I say its normal for a stock DV. Im used to it and can compensate for it by changing my driving style. Slow the rate of throttle change on a 'down-power' This will prevent the DV from opening, and allow the compressor to slow down by itself.
