i want to get one of these for my 1991 ford bronco and was wondering is it easy to install or do i need to make modifications to my computer does it set a new rev limit and top speed or just add power and wat kind of power increases should i expect from both levels

The tunes can do any of the things you mentioned, and there is no need to modify the PCM.
The chip installs easily right in the J3 service port.

Thanks

the two levels that come pre-set in the chip wat power increases do they give me and do i need a custom program to raise the rev and speed limit
