I am still a little undecided on which cam i want to put in my lq4 and was wondering which would be easier to tune for. the truck is an 05 rcsb that has the flex fuel system. not concerned with still being able to run e-85, but was under the impression that they had bigger injectors. truck will have e-bay long tubes and "catted"y pipe, along with a 3000 stall, and 3.42 gears. the two cams i am considering are the tsp 224r on a 110, or the tr230. i realize the two cams are quite different, but if one is easier to tune for, that might help me make a decision. any help or opinions are appreciated.
