Ok guys everyone that has been trying to help out thanks so much we have found that the problem with this has been happening to alot of people.....(after searching on ever evo forum known to man)
The Situation: boost creep cause from a free flowing system.
I have an entire exhaust system....Megan Racing mani, o2, downpipe, testpipe and straight pipe(no muffler)..ALSO AMS fmic , ams licp. ALL running on stock turbo.NO fuel mods except SAFC 1
Boost Controller: Turbosmart Eboost- 19psi set
Basically my system just like alot of you is free flowing trying to save alot of time i have called every performance shop in the world to try to get some help on this.. Here is what i got....
Extreme- said nothing except they need money to tell me anything. But they did say i should just turn the boost down.
Buschur Racing- guys were awesome to speak with....they say basically either port the wastegate or swap to an external wastegate, or get more backpressure with muffler or cat.
Megan Racing- they have not run into any problems with this yet but am glad i have brought it to there attention. Basically i have not enough backpressure , they recommend running a muffler , porting wastegate or going external wastegate.
Basically ive come to the conclusion that basically sucks, it looks like :
A: Fuel pump to quit from hitting fuel cut at around 5-7 k rpms
B: Muffler- at least to stay in specs as much as possible with the emissions.And hopefully create some extra backpressure.
C:After ive done this hopefully iwont need to but the last steps if this doesnt work port the wastegate area and if that doesnt work, custom external wastegate.
****Keep in mind this was also because it is winter(Dec./Maryland...20 to 40 degs)and that i have found from everyone that has helped me......the freezing cold air is also causeing some boost creep problems and is part of the problem.
Please post any info or help u may have for this topic for me and others.
