D1SC 4 inch pulley t56 swap 584rwhp 532rwtq Thanks EFI Alchemy!!! Last week, I had Efi Alchemy tune my bird and put it on the dyno. I was guessing that it would do about 530ish to the wheels and was floored when i saw 570 on the first run. The last time it was dynoed it put down 510rwhp and 456 rwtq. This was throw a stalled, and slipping auto. Efi swaped the old auto for a t56, installed a strange 12 bolt and a bigger filter. Most of my mods are in my sig but its pretty much a 347ci ls1 with forged pistons, ls6 and heads with a d1sc (4inch pulley) fmic and meth. The car pulls ******* hard on the street. I dont think this bfg's are going to last long....
Also, I would like to thank Doc, Rob, Mark and Brett at EFI Alchemy for all there help, the car wouldnt be half of what it is with out yall's help. Now i got to go find some cobra's
