hey guys, i am getting my car retuned and i am most likely taking it to a different shop. the original shop used a dynojet, the new shop uses a mustang dyno with eddy current. i know that typically a mustang dyno reads lower numbers than a dynojet, other than that is there any pro's or con's of getting your car tuned on a mustang dyno vs a dynojet? also, i know everybody and their brother says not to push a stock shortblock past 450rwhp, what number should i start freaking out about on a mustang dyno, 450? 430? Thanks.
