      <content:encoded><![CDATA[Hi, I&#039;m pretty new here and have been scanning through posts for knowledge,most of which are very helpful but I have a question about stroker kits that I need help with. I have found plenty for the 5.7 hemi and even the 6.1 hemi but none for the 6.4, which is what I have. I am currently battling myself over if I want to make it a 426 or a 440 but that&#039;s outside the question. The real question is will the 6.1 hemi kits work on my 6.4? from what I understand the only difference between the two...<br />

      <content:encoded><![CDATA[Hey guys. I&#039;ve got a few questions. I&#039;ve got an 03 SRT4 with these mods (that I know of): Mishimo radiator, AEM CAI, BOV, and exhaust. I just bought it and those are the only things I know for sure. I&#039;ve never had a turbo&#039;d car or a 4 banger. V8&#039;s and supercharged are where my little knowledge is. So here&#039;s the questions.<br />
1. What&#039;s the best sounding exhaust (deep sound). I&#039;ve heard some SRT&#039;s sound like some damn V8&#039;s. Impressed me. <br />
2. What are some good mods to start out with? Plan on...<br />

      <content:encoded><![CDATA[So awhile back my srt4 was boosting weird. It would boost perfect then the next time it would barely build. I quickly found out that my air filter had fell off and the compressor wheel had been scarred a little on the leading edges. I took it out and put in a billet compressor wheel, but now my car will only build up to 11 psi than quickly fall off. I have done several boost leak test and cant find any leaks. I have unhooked the vac line going to the actuator and even tied the wastegate shut...<br />

I&#039;m aware of what they are but my question is would deleting the vacuum lines from the 3 solenoids and leaving them to vent cause these codes. The red hose is still going from the TIP sensor to the charge pipe with the bov. Not sure if it has a staged pcm but has s2 injectors and wg (So I was told ). Every time I hit the gas it bogs so its impossible to even move the car. It idles perfect ! Any help...<br />
