My Thrasher chip won't let me start the car unless it sees over 10 volts at startup. Other chips work fine. The new battery I have in there now is a WalMart Everstart battery with about 525 CCA. I just can't get it to start the car with this particular chip since voltage is dropping below 10. If I buy a better battery with more CCA, will this keep me from dropping below 10? I was thinking of getting one with over 700CCA. I hate not being able to drive with my favorite Thrasher chip.

Well, the battery replacement did it. The "new this year" battery I had with 525 CCA went back to the store and I replaced it with a 700 CCA battery. Now, the car starts just fine with the Thrasher chip. It's a good thing Wal-mart will take back anything. I only used it for a day. 
I can't remember, for sure, but I think that maybe the Thrasher with the anti-theft trick doesn't work well with low voltage, and the other Thrashers are Ok. But since you got another battery, it doesn't matter. I have both types of Thrasher, but the anti-theft one is such a pain if you take the car to a shop, or go somewhere with valet parking. I like other anti-theft tricks better.

Did your fuel pump kick on when you put the Walmart battery in? I put a new battery in mine the other day and now mine won't start. It's a 650CCA Do I need a 700+CCA battery?

It needs GOOD, CLEAN connections on all grounds, pos wiring, to help avoid the high voltage drop.

Hi torque mini starters probably help as well.
