squishy332000 said:no ported head!!!! fnf did my port work on the turbo and manifold, i can;t hold hom without water injection because of the big injectors, i can;t explain, if yhou wanna know, talk to aaron at realtune, he tuned the car, basically if i had rc 650's, i could have made 410 or so off hom, once the big wheel goes in, it should be easily 450 in hom, probably more, it was also just straight c12, i tired straight c16 as well, and that still didn't work, but with the meth injection it is now working, and pulls very hard!!!
