Just like the title says - which one? Considering getting the pulley and tune combo. Is the ECU Tuning Group's tune worth twice the price of Eurocharged? Is either even worth it? Will the ECU in the F-Type eventually negate the gains of the tune?

 

I'm kind of curious of this as well.. Eurocharged seemed to be priced pretty well compared to ECU Tuning Group considering the performance gains.

 

I wouldn't go with either until I see (1) a set of dyno curves; and (2) assurance that it's easy to reflash the stock ECU map in case I need to sell the car (or take it in for service!)

 

+1 I've been thinking about a tune myself.
Ran across this while surfing. Anyone heard of 'em'?

Agree before and after dyno would be preferred. Some of these numbers I'm seeing online seem too good to be true especially without a pulley or better fuel... unless the factory tune is overly safe.

 

I'm interested in this too eventually. Would be good to hear details of anyone that has actually purchased ?

 

Regarding #2 - that's how it worked with my Viper. I had a DCT programmer with a couple of custom flashes in it and a slot for the stock flash - could flip from one to another in a few minutes any time I wanted. Something like this for the F-Type would be good but I think the flash alone without the pulley change is probably not worth the effort.
