I had the exact same noise from mine. never resolved it but sold it. I was worried though done it when it was stock too. Dont know but check all the manifold bolts I never got to the lower ones?????? it sounded like a belt up high when I backed off the throttle
After changing the rail, pump and injectors to suit the e85 can u have a tune still for 98 and 85. Basically can u still run 98 with the upgraded system or is it toooo large for 98? Does that sound dumb???? Its early morning forgive me.
I might lack some power but I will say if we hit some twisties look out cause dam even stock suspension made my T feel like a boat! Sorry ill stop the mean words.
You prob wont get any power gain by adding a cooler without a retune. Although u will suffer less heat soak. U will be able to push more power than before with the monzo only with a retune.
Possible yeah but did they suggest any other mods you may want to do to ease the load. Maybe a cooler. Id say at that PSI on a stock cooler isnt something I would do. Not that I can talk I have an F6 cooler.
