Got to see something interesting today. Guy came in with an 8.1L whipple he runs almost the exact times I do 1.9 60ft 9.0 1/8 @76 mph. The only mods to this truck are true duals, shorty headers (stock cats) and the whipple. Took it for a spin and found it was lean all over the place except at wot where someone had tuned it. It was still pulling 5 degress wot and the tranny tables all looked stock.

For the mods I was suprised at the times hes run I expect to knock a couple more tenths off in the 1/8th with a proper tune. I referred him to the site, he plans on building the 8.1 to a forged 502. This should get good.

Now to start researching the whipple piggy back, anyone familiar with exactly what tables it modifies and how it does it?
