This is the problem with this kit. The piping of this kit is shady at best. I know some will come to the rescue of the STS kit but with some better engineering this kit might of been a good cheap FI option. I hope you didn't pay a lot for this kit. No more than $2500 I would hope.
I know some will blame the installation of this kit but it's only half the problem.
1. The inner cooler is WAY to small. They have a new one but it'll cost you to upgrade
2. With an oil cooler, you have to remove part of the piping to change the oil filter
3. The kit will never be allowed in a city that has noise restriction
4. DO NOT ADD A METHANOL INJECTION OPTION! It will rust your pipes!
I can continue forever but I will leave with lesson learned of an unproven kit.
