Ive already bought a pre-tuned ecm with a dsp5 switch and ive been running this about 6 months. Ive been happy with the setup but im looking for a more intense "race" tune and id like to play around with all 5 tunes altogether and add lope if possible. Honestly seems like the old edge setup i had was more powerful and i can't tell much difference between the 5 levels i have. Finally i'll get to the question. Is it a good idea to buy the v2 and try and learn the efi world or is it easy to screw up something good? Can i make adjustments to the tunes i have now? I'd love to cruise around with the laptop and do things my way but i have no experience. it seems like theres alot of good information on the site about tuning but it doesn't make much sense to me without the v2. Any insight would be awesome. thanks.
