I prefer a load bearing (Mustang) type. I'm sure all of the dyno vendors have improved their offerings over the years, but at the end of the day I'd want whatever my tuner felt would be the most appropriate tuning tool for my needs.
This is really the only purpose of the dyno - for tuning and benchmarking. Numbers can vary greatly from one dyno to another.

I don't really have a preference and Darren doesn't have one. However, my car was dynoed at Futral motorsports when I wanted to get numbers out of it. I have a few buddies that get there cars worked on there and they have a dynojet. My car may not see a dyno again unless if it is ever dyno tuned by Darren in the future.

Dynojet is a free roller and mustang is load bearing
because of drag ... or the lack there of... The more "load" or restriction the wheels have on the roller, the less power it will show.. this is why other shops that i have seen will pull lighter tires and take or rear brakes and tons of other things to get the highest number possible because we all know.. numbers = sales.
If you really want it tuned right... road tune it. its by far the best way to tune a car. Its the only way i tune my car.

We do a full street tune then hit our full load mustang dyno to do all the WOT tuning. I love this dyno over my old Dynojet because it put's a good load on the car which helps alot with timing/fuel adjustments.
On our old dynojet it was common to put in too much timing and see no knock on the dyno, then going down the highway at full load the car would knock/ping. A non-load dyno can also not show fuelling problems.

Every car should be street tuned to a point of safety of course. I'm not a fan of going 140+mph in a customers car and risk crashing it.

I understand from shops prospective... Still don't believe in it.. will it be close.. of coarse.. It mainly would depend on where you live as well.. 140 aint fast here.. I would much rather tune on the street at 140 then do it on any dyno then go race someone and hit 140 for the first time on the street with a 100% tested tune. I am a firm believer in train like you race.. weather it be running, baseball or cars.. its all the same from sport to sport. Knowing where yuor going to be at exactly is priceless info.

My question in all this is if the car is tuned with 3rd and 4th gear pulls so up to roughly 140-150 which is do able for sure. Will it act differently in a 5th gear pull and I imagine you can't tune a car on the streets at those speeds. But if I were to run say the mile and use 5th gear how can you be sure the tune will hold up through the long 5th gear pull?
5th pulls just a hard when you make big power..
gear make no difference what so ever..in theory. The reason you use 4th is to get a better resolution of the data being taken thru the run.. and prevent wheel from losing traction which will mess up the data. While in WOT, you command things to happen.. that motor don't know, nor care what gears its in.. it just whats to be happy with the proper A/F ratio for your setup. If something goes wrong on a long 5th gear pull , its not because of the tune but because the parts cant handle it.
As for street tuning.. Think about going across lake Pontchartrain when nobody it there.. That is exacalty what its like where i tune. So 140 or even 190 is not an issue with cars or road space. My car gets there quickly, then i shut it down.. really about 1.5 miles for everything..

Okay good point I get what your saying and lake Pontchartrain without anyone there now that would be fun. I was thinking that since the load on the engine should be higher that would make a difference in a 5th gear pull but I understand what you are saying about parts being the real issue.

I have tuned on all the major dyno brands and I have found the Dynopack to offer the exact same readings/load etc as on track or street. Problem is you wont find many shops willing to pay three times the cost of a Mustang, or twice as much as a Dynojet for these results.
