I thought I had posted an introduction thread a while back when I had joined... but apparently not. So, here I am! I tune one of the old boat cars, an '89 Chevy caprice with a 350 TBI. Been messing with the chip tuning for about 2 years, finally put in an WBO2 sensor. Seems like everything here has a steep learning curve to it. I spend most of my time over on TGO, but branch out to different forums. This one in particular has a lot of great info for tuning, so I'm glad to have run across it!
