I have got an issue that I hope you can help me diagnose. Currently I have 80lb injectors and a Walbro 255lph pump a TT chip for e85. Have upgraded the return line to -6. The feed line is stock. I have an AEM boost controller. The car cuts out in 3rd gear at WOT. If I back off a little it will come back. I pulled the tank to check things and upgraded the pump to a DW301. I tried it after the pump upgrade and same issue. The cuts out at WOT and falls flat. I have a scanmaster and the O2s start dropping at WOT from 800 to 700s and so on.
What are the next steps in problem solving using the scanmaster. I have read it could be a number of issues, coil pack, cam sensor, MAF, plugs... Is there a logical progression. I don’t want to throw money at parts hoping something will work.
