So without going into too much details just yet.
Here are the results of stock vs Eurocharged caned tune. Mustang Dyno used
All done same day similar temperatures. Stock peak RWH 359, tuned peak whp 366...
They just did a calibration of the dyno before my car, for references a newer z51 corvette with headers put down 420 whp .

Comments from the dyno operator/tuner "way too rich, only timing parameters were changed on top end" This confirmed my initial tune impressions, felt no different than stock. These issues I had already tried to address with Jerry prior to the dyno session.
will be asking for my money back

 

So how much did 7 hp cost? I've been contemplating a tune only because I modified my cats and would like the codes it's now throwing tuned out.
So I thought while "they " are messing around might just as well add some HP. But... maybe not!

 

Donr ut a rubbish blanket on all tunes as stated previously I have gained 25whp and .5 off my e.t but that was with a custom dyno tune

 

Long time ago: 4.0 , 2.6H TS with 1.90 SC ratio ( 16.7PSI ) and AFR 12.5 : 522bhp / 640Nm Stock tune. AFR 11.5 - about 8hp less.

EDIT: wrong thread

 

Waking the dead. What ECU is being used here?

 

The 4.2 X150 is Denso, the 5.0 is Bosch.

 

I will correct you a little 5.0 XF xfr Xk XKR and probably xj up to 2014 are denso as well, or at least all the ones that I have tuned. 2014 XKR last month was Denso , two XFR s over the last few months were also Denso . Maybe I just haven't run into the Bosch ones but I suspect they are all Denso till 14
