I only made it out for 4 test/Tunes last year. The car did not run what I hoped for. The new 505/w crossram is being more difficult than I planned. The car should run 10.50-10.70 the best I ran was 10.86 with a single 4. So this year I'm changing converter and maybe lose a little weight. I going to run some Friday night test/tune to get it figured. I hope to have it figured out for the MELTDOWN drags at Rockfalls in September.
