All Hail Megatron Build - MAP 2.4LR by Levar

I need some help fellahs. I have received the same P0171 engine code twice over the past week. The first time I received it, I changed the spark plugs and within two days the code came back. According to the code print out, it is caused by either: ignition system faulty, fuel system faulty/injectors or pressure, vacuum leak, or engine mechanical condition. I am starting to believe that it is the coil on plug system that I have as it was only tested up to 32 PSI which is where the car currently sits. I do not have a boost leak as I have checked that up to 30 PSI. Does anyone have any feedback about the injectors or either something mechanial that could be contributing to the issue? Lastly, should I run the stock OEM coil packs to keep the set up simple?

I have my wife pulling her hair out with all of my turbo "talk". 

I have the stock IX turbo and right now is a good time for me to upgrade and get the EVO taken care of.

Based on the power I made from the EF4 (513whp and 470wtq), I know that breaking 500whp will keep a smile on my face for a long time. As for the torque, I am pleased with that as well but I need something that spools faster to get the power band pushed to the left more for how I use the EVO. 

This is why I have opted for these two turbos as they each flow in the 49 to 55 lbs/min range which will be able to achieve at least 475whp and nearly the same 470wtq as I had with the EF4 but sooner. 

When I had the EF4, I achieved those numbers on a single Walbro 255lph at just 32PSI. The turbo is a BEAST for those that are intending to drag race. I have to keep my power goals realistically around how I now use the car.

I got a new toy in the mail today - FP Red. I am very excited to see what it does with the 2.4LR on E85.
