I got my car to start and to idle after the headgasket replacement. The starting problem was the car was off timing and the idle problem seemed to be an ignition coil. Now the car idle horrible at first start up but eventually smoothins out and sounds like a misfire would. BUT when Im driving my car falls on its face when I hit around 2psi and wont go pass 2psi. I have adjusted the boost, changed the spark plugs, replaced an ignition coil, and no progress it still does the same thing as soon as the boost starts to climb above to my car seems to start bogging.

ANY input would be very useful!

THANKS

 

Does no one have an input. I'm thinking it my be that I need a valve adjustment too. I have an AEM EMS so I had to put an aftermarket MAP sensor it also works with my DEFI gauges as well, Do I need to replace that. The AEM is telling me nothing when I plug my laptop into it. If someone can tell me what to look for when I plug into the ECU that would help too.

Thanks Guys!
