LB9 computer reprogramming?
Hey guys, I was wondering if anybody tried one of those plug-in performance computer chip programmers on an LB9 engine. The companies always make crazy claims about their HP and torque gains so I was wondering how they add up in the 305 TPI engine. Thanks!

not on our cars. I think they just advance the timing, but it doesn't do wonders. A good tuneup will net you more hp...

You think so? I was browsing on ebay and I found this:

I was wondering if anybody tried this or something similar

yeah, plenty of people have gone through TPI/TBI chips, but I think thats more for convenience thing, like people removing vats and smog type stuff... Some people think its worth it, others don't...
