i know you asked me this before, but I’ll repost it here to be seen. Plus a couple other things I thought of
Only two issues I've had is with the EGR and the Modbox supplied fuel pump. Other then that, everything runs well.
The original EGR does not fit, it interferes with the coil pack. I flipped it upside down, and everything fits ok, but there is not a good way to route the flexible extension tube that goes from the exhaust to the EGR, and with too much vibration it will break. I've tried re routing it a few different ways. I seen someone else used a EGR from a Mustang that has the bung facing a different direction, claims everything fits much better, I will try that eventually.
Modbox supplied fuel pump took a shit after a couple of months, just seized up while driving with no warning. Ended up installing a Walborro 255L pump from Summit and has been good ever since.
Biggest complaint is the placement of the throttle body requires me to remove the intake tube to change the oil. The tube goes right over the fill cap. I also kept the original air box instead of cutting it up and installing the cone filter that came with the kit.
I like that they have extra NPT ports threaded into the manifold. Makes it easy to a vacuum gauge or whatever later if you don’t do it right away.
I also like that the mounting bracket for the TB cable is adjustable, so you can adjust out the slack in the cable. All the aluminum bits seems well made, it’s just the ancillary stuff that isn’t impressive. For the price of the kit, I’m ok with it.
Fuel economy went up from a solid 17 to around 20. Still have not had it tuned.
