I must confess I'm a little confused.
Can you give me the best possible ET a '99 Lightning can run with a Chip and Filter ONLY mod? Also didn't the guys have drag radials on ?

I think my 13.658 (I think rather average)is well within your parameters for a believable time. But what is the best time I can hope to accomblish according to
your best caculations ? No flame just curious.

And finally, I have talked to some real solid people who say it is possible to
pitch a perfect game, granted it doesn't happen very often but it does happen from time to time. perhaps these guys had a perfect shallow stage,a perfect launch under perfect conditions (a good tail wind)and had an exceptional Truck in perfect tune. It takes a real sad character to lie about ETs on the net. To what end ?I don't think any of them let alone all of them are lieing, do you ?
Bottom line, perhaps you are mistaken.
