7AL3 question
 

I have recently experienced an issue with the launch rpm chip, When I put the car on the chip (5000), the rpm's went past the chip and up on the converter (5600). I put a 200 rpm lower chip (4800) on the next pass but my recorder shows, that the rpm's were (4950). I know there probably is a variable on the chips but how far off is an allowable.

I looked at previous runs and the rpm's at launch are consistent. I think the issue is in the 7AL3 box. Any idea's?

Kevin, + - 50 rpm not unusual on a chip.
I had several issues last year with my 7 AL3 .
I sent it to TechWest Services ,and it came back better than new.
