I am nearly completed with my t2 conversion. The only thing is i need the halteched tuned. I have no idea what to do because the guy workin on my car, said i can't drive it unless they tune it. Then take it to a dyno and tune it on the dyno as well. I asked around and few people told me that as long the car is tuned right i don't have to take it to the dyno. Another reason i don't want to dyno the car, is that they have tendencies to blow peoples motor on the dyno. Say 2 out of 3 times. Please help!

Thanks

the dyno is a tool for tuning. it is best to tune on a dyno.
the dyno will not blow your motor, shitty build quality and shitty tuning will.
only reason it will blow is if the builder or tuner did something wrong.

So what about street tuning? That should be fine right?

Street tuning can get you all the driveability you want and 90% of the power potential. Street tuning is safe when performed by a competent tuner. Dyno tuning is more controlled, safer from the stand point of not doing 4th gear pulls to 130mph on the street, and can produce a more precise tune. Even if the car is tuned across the full range of load v. rpm on the dyno there will typically be corrections that still need to be made on the street. The wideband logging capabilities of the Haltechs makes street tuning pretty damn accurate when it's all said and done. I like dyno tuning just for a confirmation of what we've done on the street.

If you are not 100% confident in the tuner you have in mind find someone else. You have a lot of time and money invested in a swap. Now is not the time to worry about spending money. A good tune will produce more power, better driveability, and most importantly your own confidence in the car being reliable transportation. Maybe start by making a post in Haltech section looking for tuners or even giving Haltech USA a call to find one in your area or someone that travels.

The other option is buying a quality wideband and doing it yourself. Tuning is pretty intuitive. Making a car idle properly is about the hardest part IMO. Just make sure the car is rich across the board and slowly work for rich to lean. For timing you can always use the settings in one of the Hitman maps. They're very conservative and will produce reliable results but will leave noticeable power on the table.
