Weird that you've had this on the car for a few years with a few thousand miles, with no issues. I have heard some Gen 5's have eaten material on initial startup, but it is strange that this happened out of the blue.
May be wrong, but you would have to do GT500 manifolds since the driver (passenger?) side cat is attached. Would likely be same cost as doing headers with no cats.
OP, if you are worried about cooking cats, then just do cat deletes. There are a few brands still selling them. If that is too...
Anyone holding onto a Roush 2.3 supercharger kit from 2015-2017? I am not interested in piecing together a kit from a bunch of places, so a complete kit is ideal!
Lund is responsible for your car. VMP is responsible for selling you things.
Listen to Lund. There is no reason to try and hit 700whp on pump gas. VMP's 69mm throttle body has been prone to failsafe issues, so the Ford 65mm is typically preferred.
End of the day, listen to Lund. Your smart...
This thread has spiraled away from your original question, so I will answer it now.
800hp is too much for 93 pump gas, even with twin turbos. With turbos on the 5.0, the limit is really 700, but even that is pushing it.
I would recommend the Hellion sleeper kit with either the 62mm turbos or...
I would save yourself the headache and just do the ESS.
You will enjoy the Lund E85R tune for one day, and then you will get used to it.
ESS G3X, 120mm pulley, and I would get some free flowing exhaust just for safety, but you will be perfectly content for a while with 650whp.
You'll start to run out of fuel system. There is a clear reason why Lund recommends a Fore dual-pump system with 2x 285 pumps. What injectors are you running? ID1050X?
At WOT, the DI is not really doing anything for power.
Obviously my car was built on a Wednesday, and the computer was built on a cloudy day, so your Revision 87 base file is NOT going to work on my car.
Please start from scratch. I will not be satisfied unless we do 34 logs, thank you.
There are only SO many variations, so it is to a point where base files for a certain injector, fuel, MAF housing, etc. just works and does not need 12 revisions to "dial in" a combo, unless it is completely foreign
