Hi all i have an '89 3.5 efi. Towed for the first time with it this weekend and it struggled abit on the long up hills. Is there anyway of getting more power out of the engine reliably. I'm not looking for daft levels just abit more to make towing easier. Thanks in advance. Oh better say the whole vehicle is completely as it left the factory so no mods at all

When you say it struggles a bit, what are you comparing it too?
and what weight are you towing?
Jeep Grand Cherokee 4.0l
and towing around 2.5 ton maybe a bit more.Cheers, there are a few products that might help like the 5.0 stroker
