If $270 was for the kit with installation, it's an awesome price. If just for the kit, you need to bring vaseline in with you when you pick up your truck.

The basic kit from engnbldr is $54, and $64 gets you a kit with a steel rail guide (rather than the stock nylon guide).

It's possible for a chain to jump a tooth, just unlikely. Especially with the guides still intact. I call BS on the diagnosis. The truck would run like crap with the cam off a tooth (either real strong off idle, but flat on it's face above 3,000 rpm, or no power until above 4,000 rpm).

The reason the timing looked so far off was the fact that the TPS was out of adjustment... It would be around 12* BTDC without the jumper (or with jumper but TPS out of spec), and 5* BTDC with jumper in place.

A good way to get everything close enough is to loosen the TPS, install the jumper, and rotate the TPS until the idle drops. Set the timing to 5* BTDC at 600 rpm. Then wiggle the TPS back and forth until you find the closest adjustment between low and normal idle. Tighten it down, remove jumper, and drive.

Get your truck away from these hacks! <img src="/forums/images/graemlins/scared.gif" alt="" />
