he said e-dyno

 

I prefer dynapack dynos to all others.

 

I thought stock Zs put out 230WHP?

 

All that and no ECU reflash?

 

what do you suggest for a replash..? what will it really do gain 4-5whp and torgue.

indeed I would like to get an Osiris flash, but no one in my area is an Osiris Tuner.

I could use Cobb, but that thing is BS.. Unichip, even worse.

at this point the numbers dont really matter, and likely will not spend money on a reflash, when I will probably go SC with a vortech setup ( will use 3.12) by the end of the season.

then we'll see some accurate FI power figures on the Mustang, instead of the usual 405-410whp, that I see all the time, with a Vortech setup.

I suspect the Mustang would show 375whp range, with 3.12pully, good tune and my current setup. therefore otherwords a 400-410whp range on other dynos.

 

Have you looked into the sts rear turbo? I've read nothing but good about it. When I'm ready to boost my stock engine that'll be my choice.

 

reflash on N/A is not as drastic as you say...but is not just about 5~6 HP gain but the change of the power curve which you do feel..
