Well when my 92 was stock, it was a good truck, not a rip roaring monster but a good truck. it should have good low end grunt (high torgue and low gearing) then yeah, kinda mild, and good cruise characteristics. after a compete re-build it should run good.

Now the big question, did you time it correctly? If you don't know Mitsubishi's there is a secret to setting the base timing correctly. you have to ground a ECU Pin to put the ECU in Timing mode, so it doesn't change the timing at different RPM and Load. Crucial to a good running '92.

Check my site http://mmeierle.com/mighty%20max%20info.htm or the manuals section on the site for wiring diagrams.

here's the connector you have to ground for timing.
