I am getting very close to hooking up my Haltech E8 and I was wondering How hard is it to street tune or do I need to go to a dyno. I would like to street tune it. I have a S5 turbo II motor with a knightsports turbo and I may be running 1200cc secondary fuel injectors and 750cc primary fuel injectors. I still need to get me a wideband gauge. But I will be using the plug and play harness with my Haltech E8.

 

street tune is fine if you know what your doing go for it.

 

I always like to rough a tune in on the street before setting the car on the dyno. I can usually get the off boost areas very, very close on the road. I don't like doing high speed pulls on the road for a lot of reasons so I try to save that for the dyno. Get your wideband hooked up and go for it.

Where in Ohio are you located?

 

I like to do all tuning on the dyno then take it on the road and make sure its all smooth. And i do a few pulls on private roads to make sure afrs are close if not the same as they were on the dyno.
