I on the other hand prefer e tuning, although I wouldn't do pulls in 4th but 3rd due to speeds. Dyno tuning is an artificial environment that the engine gets tuned to really, but that's just me. I understand I may be in the minority with regards to this.
My worthless opinion...
Your actually doing your tune a dis-service really. The better your datalogs are the better your tune will ultimately be. Can be it be done with 3rd absolutely yes, will 4th gear be better...absolutely (*confirmed by Ed an actual tuner). An e-tuner can only tune based off the datalogs you give him. Give him more logs and better quality logs and your tune will be better.
FWIW, I've never seen a e-tune outperform a pro-tune, same car, day, fuel, dyno. Literally last night my buddy re-tuned his etuned car. They ran it on the dyno before touching anything. Cobb was used for both the e-tune and the protune, the protune made ~15wph more on top with higher gains in the middle. I will not mention any names to save them the embarrassment but it was a popular e-tuner.
Just because your protuned doesn't mean you shouldn't datalog. You should always datalog your car to see how your car is currently running as things happen as time goes on..boost leaks, sparkplugs wear out, coils may go, loss of compresion, etc.. Just knowing for example how much timing you run optimally is useful to understand if something is limiting power output.
