What to listen for...
I am installing a procharger, injectors, and a nelson tuned pcm. I completly trust that nelson did a great job on the tune based on the reviews I have heard, but I just wanted to know what I should listed for incase something happen while tuning. I have heard terms like detonation, knock, etc but don't exactly know what they sound like so an example of something that makes a similar sound would be helpful. Thanks

Detonation sounds like marbles in a coffee can being shook around. If you hear this let off the gas right away.........Knock is what the computer reads from the knock sensor, do you have any type of tuning software or even the aeroforce guage that can monitor Knock retard? The guage is pretty neat by the way.

What size pulley are you going to run first off. I would if at all possible run a bigger pulley till you get the bugs ironed out and to make sure you arent getting knock. The PCM will pull timing even if you cant hear the knock. Anybody around you have a laptop you can use with AutoTap or something? Maybe it would be best to get a wideband, not just for now but for long term use or that scan gauge. Not gonna bash Allen, but no mail order tune isn perfect.

I am going to be looking into the new autometer widebands you posted about a little while ago. And I agree, is hard to be dead on with a mail order tune, but I am sure he is close. Thanks, and anything else I should be listening for, please post up.
