vy ss kw's

Here is my old engine with an auto and big heavy mag wheels.
Stock with exhaust and OTR CAI maffless tune.
Chuck another 10rkwk on that if its got stock wheels.
The graph shows the difference between stock and exhaust with OTRCAI with maffless tune.
The person who tuned it is NOT my current tuner.

Mafless tune wont give you a great deal of extra power unless you have other accompanying mods.

Have to call bullshit there. Mafless tune is not reliant on other mods to get power. A stock LS1 will get around 210-220rwkw stock with a mafless, or around 20% increase.

A custom mafless tune is around $1000 and a mail order tune around half that

VY SS has 235 KW at the flywheel
Clubsport 245.

Your flywheel kw's for the series1VY SS is correct but your HSV figures are a little short.
HSV VX1+2 = 255kw, VY1 = 260kw, VY2 = 285kw , all with Gen3 5.7Litre
HSV VZ = 297kw 6.0Litre

Thanks for clearing that up.

mine has 223rwkw with just a cat back exhaust and otr, that was the last time i got it dyno'd. since then ive put on extractors and modified the cat pipes. coming soon will be high flow cats and a mafless tune. then i should be looking at around the 260-270rwkw

That's a big increase with just an exhaust upgrade. I have a full sports exhaust with high flow cats and tune and only got 230 at the wheels. I would expect 260 to 270 if I installe a can but not just if an exhaust upgrade.

yeh i dunno what the previous owner did to it b4 i got it apart from dual 2.5inch catback, but yeh i got 290.1rwhp which is roughly 216rwkw with only catback and otr. i was hell suprised that it didnt make more power as i can keep up with my mates sv8 which has 340rwhp(253rwkw).

you wont see anywhere near that without a cam change etc....

So how much power would a set of high flow cats and a mafless tune give me? something like 40rwkw more?

It sounds like from those figures you already have a maf tune.

If that were the case, I'd say 10, maybe 15 if your lucky for mafless and cats

EDIT: If your running an OTR you must be mafless now??
