I finally saved enough to get a limited slip differential installed at Behe Performance. Here’s what it looked like the day after I dropped it off:

I was able to get the Quaife LSD through a great group buy on NAM. The price was almost $700 less than I’ve seen it listed at some (unnamed) major online catalogs.

In the past week I’ve had the pulley belt replaced; control arm bushings replaced (boy were they shot); and the oil pan gasket replaced. Along with the Quaife and dyno tune, I’m getting the shifter cables replaced and a new clutch. I should be good for another 90K miles….

John’s tuning work is really impressive. He was able to get almost an additional 10 horsepower over my previous (non-custom) tune from MTH. That brings the total to 197 hp at the wheels on a relatively humid day, no less. More impressive, however, is the increase in low-end torque. Peak Torque is now almost 167 ft lbs, with 166 ft lbs at 3250 RPM. This with no work to date on the head or header. On average it’s about an 8 percent horsepower gain, and 9% torque gain over the MTH “tuner file” tune, (that’s an incremental gain over a fairly strong tune to start with.) John’s tune (with pulley / intake / exhaust) gives me a 23 percent increase in torque and a whopping 32 percent increase in horsepower over stock. More power, ho-ho-ho.
