Sct X4 - With Custom Tune

[karlp2]

Spoke to my local tuner, was looking for a basic tune over stock for my G6E turbo. I have a fuel card through work but in NZ Shell/Z only do 91 and 95 octane so run 95, when have cruises come up I buy 98 elsewhere. Tuner said he can tune to suit 95, he didn't recommend tuning for 98 if dropping back to 95. His alternative option was for another NZ$600 he could do both tunes with them loaded onto a SCT X4, for clarity he is doing a full dynotune. Bit of a pain Shell not doing 98 otherwise would just tune for that. Is the tuner right with what he's saying or do I not really need to worry if tuning for 98 but doing daily driving on 95? Know it's not ideal but if I just tune for 95 only he's talking 15-18kw less at the flywheel between a 95 and a 98 tune. 95 here in NZ is over $2 p/ltr, 98 is another 10 odd cents. If it wasn't my daily I'd just stump up for 98 myself. Car goes in next week for a tune, just need to guide him on what I decide. As said know my situation isn't ideal but would appreciate others thoughts on which way to go. Cheers.

If you're going to be driving it on 95, tune it on 95.

You can always go back later and get a 98 tune - sure beats going back later and getting a new engine
