Savior:
Glad you had good results.
Just FYI, they have you pull the fuses to save your battery during the upload of the tune.
Downloading the factory tune and uploading the SCT tune takes about 5 min. and having the electronics on can drain your battery (it did on my SHO as it had a weak battery)
Also, if you've played with the device, you can build off the tune you have by adjusting fuel, spark, limiters, fan control, etc. and saving the info.
I wouldn't do this unless you comfortable tuning, but I did this with my SHO and liked the results. Talk to NPG, but you might just be able to make a few minor changes for your new mods and not need to spend $70.
