Maybe somebody can help me with a problem. I have a 2005 EVO VIII and I took off my EVO IX Bov to try a Greddy RS Recert for a few minuets and did not like it. I then Switched back to my EVO IX bov and the car ran nice until I hit the factory 20 psi and then it runs like crap. The car only runs like 20 mph and cant build boost. I hooked everything back the way it came off. I only unhooked one vacuum line. Please help.

another hose fell off from somewhere.

Try disconnecting the negative battery cable for a few minutes to reset ecu,see if that helps.

Ok because I only disconnected the positive. Ill check the hoses as well!!

If it hit 20 psi once, then won't accelerate or build boost, you blew an intercooler hose off.

ak47po is correct, disconnect the negative terminal from your battery. I would be safe and wait about 10 minutes (overkill for many, but that's what I would do). Re-check the vacuum lines. If the intercooler hose blew off, you would know right away (stumbling, rough acceleration). Good luck.

yep ive had this happen. i clean the hoses with alcohol before i tighten down the clamps to help them from slipping due to blow by oil getting all over them and not getting a good straight clamp.

I've had this also, just on my eclipses 4g63. It happened to be a silicone coupling hose that came out of the IC that had a 2-3 in. tear in it

Thanks guys. The Car is in the garage with the hood up. I will check these issues out tomorrow morning!!!!!!! Any more ideas keep them coming. Before this I never once had an issue with this car. This is a bummer...

going by what has been done and the symptoms
it sounds like a massive boost leak like everyone else has said
I had a FMIC pipe come off my old sr'd 240 and the same thing happened

would a bov being intalled backwards cause this issue? maybe that?

i know you said you put it back the way it came out, but something like that could just be a d'oh moment.

Well just wanted to say that I got the problem fixed. Found out that there was a small slice on a vac line and the hose was kinked a little bit. Replaced the hose and she is back to normal!!!!!! Thanks for your help!

thats good that you found the problem. sounds stange that a small slit caused all that. so you didnt find any blown off intercooler pipes. good job anayway.

hawkeyez

Thanks. No I checked and there were no blown off intercooler pipes which was def a plus! Now looking to get tuned either this week or next.
