What can I expect to get out of a dynotune with speed density ? Has anybody ever used Performance Dyno in Concord NH ?:headscratch:
 
speed density

Maybe I should elaborate more. Has anybody that got a tune with the SD been impressed with it. What are the limits ? Is it a waste of time and be better off just going with mass air? Expense is always a big factor.:headscratch:
 
If expense is a big factor, forget about mass air.
On a stock truck ther is about 5-10 hp to be had by leaning the fuel mixture at wide open throttle and bumping the spark advance, course you need to find a person that knows how to tune SD and there aint many of those left.
 
I don't know much about density but I have been to that dyno before. He does ok work, I would not say that he is great with lightnings but he will try his best and be honest with you throughout. Now if you had a mustang or camaro I would say he is one of the best tuners in the Northeast.
