Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
What diff, man/auto?
Yeah mate, that's ****. I thought it would be brilliant, maybe there's more to the dyno report as well btw.
Because I do my research
VE SSV - EXHAUST , TUNE & AIRBOX.mp4 - YouTube
I was expecting:
1. The car to drive like 85% of the HARROP, WALKINSHAW, GM MOTORSPORT DEMO CARS bearing in mind the my catback, It has nowhere near the throttle response, or torque. these cars were on 98
2.about 5 to 10rwkw more than 426cuda (260rwkw)who had a gain of 30kw after fitting hi flow cats and a tune to the otr, hsv extractors and gts catback
3. To have better throttle response than a stock 150,000km ve ssv auto (my brothers car)
4. what I was promised : HM Headers = better than HSV, :SIDEMOUNT CAI = no different to otr
I paid the $3350 a grand extra for a gain I never received
well the WP kits offer a full warranty so to me that's a safer option, and you just said Yourself you did your research so why did you let a tuner make decisions about your car that you had already decided on. YOU are the one paying therefore its your call not theirs at the end of the day but I still think the gains you are after are unrealistic for what you have done.
Seriously, what the #### am I reading?
Just leaving this quote here for added lolz.
1. Do you know exactly what was done to these cars? Could it be that these demo cars are there to sell you on a product and are therefor a little more happy in the power figures?
2. This is where I want to slap you with the idiot stick. Lets drum this into your head DYNO FIGURES ARE A FIGMENT OF YOUR IMAGINATION! They are a tuning tool to see if the air and fuel ratios are correct and to make sure its a nice steady gain of power. Comparing your car to someone elses car who has run on a different dyno, different day, different temperates, different operator you are setting yourself up for disappointment.
3. I doubt it has better response.
4. HM headers are better, what size headers did you get? If you went for 1 7/8 you probably loose a little down low but make more power up top. Noise is great but unless youve got a nice cam or FI its not needed.
Did you do a dyno run of the HSV headers and OTR then compare to the HM headers and side mount? No? Ok good.
You gained 30 rwkw, on a conservative dyno. Strap it down somewhere else and it will read something different.
Just FYI, I just had mine tuned. OTR, 17/8 Headers, 2 and a half inch exhaust with a H Pipe. Made 252rwkw on 98. Now, on any other dyno, I would say youre probably sitting on 260rwkw. But being a brand new Dyno and a Mainline at that, they are CONSERVATIVE.
If you went into this wanting 270rwkw, you a) brought the wrong car b) did the wrong mods c) got waaaaay ahead of yourself.
Now, I would ring APS on Monday. Say hey, I dont have the much increased throttle response and maybe id like to make the power a little earlier. See if they can adjust the tune for you to suit more low down power.
As you rightly point out Dyno's are a tool like yourself. What was your gain? If you have read my posts and taken them in you will realise that when I questioned
the dyno sheet GAIN 30KW Frank quickly rebuttled with the stock line is with everything installed!!!
