After Upgrades Car Misfires Cuts out at WOT- Ideas????

After making some upgrades the car cuts out and backfires @ WOT . However under normal driving and normal acceleration it does fine and spools fast. It just when you lay into it.

I see you have a wideband. What is the wideband reading doing as you come up into boost? How much boost are you running?

 

[DMAC]

I have it around 20 lbs of boost so far

The Wideband is normal at idle but when I go WOT and heavy boost if goes to 15's 16's goes past what the meter can read

 

[Eric Stage I]

It's either way lean, or you're seeing the lean readings when it cuts out.
You might try lowering the boost to say, 15psi, and see what you get. For E85, I would keep the A/F no leaner that 11.5 in boost.

 

[DMAC]

Here is my read from the scan master

 

[TurboDave]

Yes, we've seen your readout 3 times already, have you tried Eric's suggestion? What results?

 

[TurboBuRick]

I would be testing the fuel pump.

 

[DMAC]

Thanks I found a water leak on a hose and after, I wanted to post my readings on my new scanmaster at the recommendation of Eric and others I get that fixed I am going to check the fuel pump again ,

I turned the boost down and its better still has it , I think it needs more fuel

 

[DMAC]

I got the heater hoses replaced

Now when I am trying to adjust the WOT fuel .... I cant get the LV8 to cycle following Eric's instructions ... is the scan master toast? IT is getting other readings..... so it is hooked up right .... Any suggestions? ( Using loud profanity and flipping off the scan master has not worked as of yet)
