We had already completed a full tune on this VY SS to give it a respectable 229rwkw. After a couple of months, hankering for some more power the customer returned wanting a Mafless Upgrade, which we performed, and gained another 11rwkw, or 5%. Well worth the effort. Owner comments lifted from ls1.com.au forum -

"Well, I had some more work done on the car over the weekend with the help of ST. Decided to do a mafless tune on the car to see what sort of increase could be achieved. After a bit of fine tuning we achieved a 240.4rwkw on the Morpowa DD Dyno. Extremely happy with the results, the car is pushing really good power for the mods it has, all I need to do now is get the power onto the strip (will probably need a new clutch for that ). Next step will be to do some CAI mods to get some colder air and after that, open the motor up I suppose. Thanks to ST for his work"

NOTE: DUE TO ONGOING DYNO COSTS UPGRADING FROM A FULL TUNE TO MAFLESS COSTS $500+ GST
