Hey guys, well the other day I went to a local dyno shop to see what my car was making after buying it 2 weeks ago. the past owner said its mods were mid lenth headers, ory, magna flow mufflers, ls6 intake , trick flow cam, and 3.73 gears, but I know the gears don't mean power. He claimed it made 347whp a while back and I'm not sure if those numbers were with the cam or not. Anyways when I had it on the dyno the car only made 320whp... come to find out later my tps was only reading 68% throttle when it should of been 100%.Will that 68% throttle mess with my dyno numbers? I am probably gonna run it on the dyno this next week to see if there is any change. That 320 just seems really low for a car that has let alone a ls6 intake and a cam, aren't there people making 320-330whp with just bolt ons and intake.

Lol

Also is it an a4 or m6

Autos read lower than manuals on the dyno..

Oh sorry, its a ls1 and a a4.

The cam I'm not sure of the guy didnt remember the lift. He said it has 344/344 duration though.

If you were at 320 with 68% throttle than I would think that sounds about right with small cam and auto.

whitev6

So you think even with the car having 100% throttle now it won't show any gains?

I was saying if it was showing 320 at 68%, I would think it would show gains at 100%.

What brand of dyno was it?

If it was showing 68% throttle there is plenty to gain. The pcm makes changes at WOT and most of the time it takes over 90% throttle to activate those changes.

You will show some more rwhp at 100% WOT but dont think you will see a major improvement probably another 10rwhp considering the duration is 344/344 just my 0.02. I had a stock cam when i made my 335rwhp with full boltons.

Im sry i misread i thought you was making like 330 but i see you said 320whp so that being said probably another 20whp key word probably i dont know how much bc i dont have a big cam like that in my car

Thanks for the info guys. I winded up changing the tps because it was throwing a code, and could of been the cause of the car not wanting to 2-3 shift. I think the shift points are all messed up but I could be wrong;when the car shifts into 3rd it feels like it looses its pep. I guess its time for a dyno tune.
