Just got back from dyno. Have a few issues.
I just finished my LS1 swap a few weeks ago and had the car dyno tuned today. I attached the results.
I have a few issues with the gauges. I put in an autometer tach and speedo. The tach needle jumps around when the engine is at idle. Is there anyway to clean up the signal?
The speedo seems to be working except at low speeds it steps down in speed instead of coming down smoothly. Again, do I need to clean up the signal from the VSS?
Thanks for the help.

Thanks guys,
As for the motor...
Stock LS1 bottom end, Crane 218/224 cam and matching valve springs. As for the heads, I'm not completely sure. The castings are 5.3L heads which was a bit of a surprise since I was expecting a stock LS1 pullout. There may or may not be any work done to them. The throttle body was polished a bit and it already had a 160 thermostat. For the exhaust I used flowmaster 2.5" kit with 50s muffler. Had to modify some Edelbrock stepped 1 3/4 to 1 7/8 LT headers to fit.
Haven't figured out what to do about a shifter boot. I'm going to run the stock console and thinking about having an upholstery guy make something to fit. The A/C unit is Classic Auto Air. Cost $600 for the interior kit. I still need to buy the compressor and brackets.
