well wont a street tune be adequate..without worry of blowing ur motor until u can afford a dyno session. i understand you wont get the full potential through a street tune but if they dial in the a/f correctly u could red line ur motor without it blowing?? since my motor is almost done id really like to know..since i still have a few more things i need to buy before i can get it dyno tuned along with the break in period..

compared to a base map....where ur suppose to only be able to drive to the tuner..but not suggested to actually drive on a daily basis..???
