Are the 918 springs from a company like comp cams, or crane??

 

comp cams

 

No, I had the springs long before the turbo.

 

I've ran up to 8lbs of boost and no problems on stock springs and stock fuel pump. My truck only has 7,000 miles though.
I can't see you having problems with only 6lbs. but you never know.

 

I'm having mine installed at Xtreme tomorrow. I'll let you know if I run into any issues. They're not going to run an intank on mine though. They highly recommend a setup like what comes with the Radix. Did they mention that to you??

 

Do you have the little air filter or the big one? What are your IATs? Seeing any KR?

I had a very similar problem when I was tuning at first -- I put on the bigger air filter (I know this sounds like mystical bullshit but it isn't) and it dropped my IATs and elimiated the "falling on the face problem" It was about 100-105* ambient at the time.

 

I think mine would be like the Radix, it is the Walbro that I bought from sts. 340-255

 

Don't know how you check the IATs and I have the filter that sts supplies with there kit. Xtreme say's there is no KR. Could I check it out without the Air filter for just a short drive?

 

I wouldnt think that it would be valve float....Maybe some kind of tuning issue?

 

Allen Nelson has sent me 3 pcm's and the forth on the way??
