Tune advice

[dave64]

I have twin 2.5 cat back, would that flow well enough. Looking for mid range more than anything. Don't redline it to much.

Yeah that would be fine. That's all I have and I still managed to make just shy of 280rwhp (dyno figures aren't gospel though) My car is stock besides the catback and monaro scoop.

Thanks mate, much appreciated.

Holden specs are in flywheel kW, correct?

So if my math is correct, 280rwhp=278fwkw?

If i can get 270kW @ 200kg lighter than a VE SS 6.0L performance should be very similar?

What the difference in Torque figures? Kw are only part of the equation, especially peak values.

I suspect the VE will have more torque. 200kg weight difference should make up for that i would have thought.

Anyone know VE manual diff ratio? Both have T56 box.

My Executive has factory FE2

 

[dave64]

My rego papers say my car is 1471kg, this cannot be correct. If it is that makes my car over 300kg lighter than VE SS

I listed weight of my car in first post as 1590kg, VE SS as 1775kg. That's 2 x 92.5kg adults

Probably a dry weight (minus fuel, oil, coolant...)

I have the exact same question and have the 10psi and a strong car, I would like to know if the guy with 100% feedback who only sells commodore memcals if they really are decent. What % gain should i expect any one got or had one? commodore tune@gmail on ebay. I will get a custom one day but to many other costs on the car atm.

Holden stock tunes are well known at being very very safe. Even better with the electronic autos you can have nice shifts as well.
