Ive got an opportunity to buy an upgraded ecu for my 91 1j that gives it different timing maps, cuts speed defencer, fuel cut defenser, boost cut, rev cut. what is the highest anyone has had their 1j revved to and still has it working? lol. Thanx!

I don't have any mods done to it besides a few bolt ons.

Diddo, same ecu, same issues. For me there's a drop in power after 6800 or so.
