No, I actually did a full port & polish on mine. Took about 3 weeks to complete and another 2 days to re-assemble the motor. I can now go up the El Cajon pass on the 15 fwy going to Victorville without having to shift into 4th gear. It feels like I picked up mainly torque and response but then again, I do feel the need to upgrade the fuel pump 'cause I'm running a little lean. Once I change that, it'll really wake up the motor. Right now I'm going to concentrate on headers, changing out the 02 sensors, upgrading the cats, and getting a custom exhaust.
yeah with a port and polish you shouold see some gain in the Pony area
