Hi all new to the forum names damien just brought myself a yellow evo 7 and the guy i brought it from really didnt now much about the car but had a dyno printout for the evo of 307bhp but its no where near that at the moment and have a few problems with the car.

1, The idle is abit irratic after slowing down to traffic lights etc it sits at around 1500 to 2000rpm the settles down after a few seconds why is this?

2, The car peaks at 0.8bar then settles to 0.65 this is from the reading on a Greedy boost gauge and greedy profec spec b. i was told it should be at around a bar?

3, The profec has been set up, well say set up all the setting have been changed etc but with the controller of on lo and on hi it does the exact same,

4, Can anyone tell from the engine bay pic what is not standard i know it has larger ic and after market manifold but can anyone see anything else

5, How good are the standard bov? cause it seems its running one but maybe this could be causing a boost leak?

 

assuming your engine bay is the same as the evo 8/9 i believe you have a aftermarket upper intercooler pipe, not quite sure what else there is though

 

take more detailed pics of your engine bay! I.E turbo and other parts that might not be aftermarket.

intercooler is aftermarket

 

The exhaust manifold is not stock.

 

Sounds to me like you may just need a full tune up. Meaning replace the PCV valve, flush all fluids, replace air filter and fuel filter if needed, and wouldn't hurt to check your plugs.

Sweet car though man! I wish I could of picked up a 7 instead of having to wait for the 8.

 

Radiator isn't stock.
