Based on my mods below what kind of WHP i will get out of my 2005 VIII . Car is running on 91 oct @ 21 psi and has a dynoflash mail in tune. What kinf of WHP increase should i see after a custom tune is done ? I think AMS is coming to vegas soon so i might go with them .

 

around 315

 

I was Thinking a little Better, MAybe 320-330. ^ funny sig.

 

Maybe if he had a set of cams.

 

You know the car is a 2005 10.5 hotside, its not a 9 - EvoIX

 

You can hit 270 whp to 320 whp depending on the dyno. Pic a dyno based on what you want to see on the graph.

 

I beleive the dyno out here in henderson is a Mustang dyno. Any lasvegas guys confirm what Dougs Dyno has ?

 

He's on 91 octane, I don't think he will dyno that high. Mabe around 290-300 horsepower if his tune is good.

 

with a base tune around 300 maybe a little less. Full custom up to 315 i would say on a dynojet

 

+1, same statment I was about to make. I drove to an area recently that only had 91 (I am tuned for 92) and my car didn't run right until I bought a bottle of octane booster and dumped it in. I am surprised what a difference 1 octane made!!

 

Isn't that terrible. I remember years ago when L.A. first changed from 92 octane to 91 octane. I wasn't able to run nearly the same timing advance on my old V-8 when they changed octane ratings on us.

 

So anywhere from 270 to 315 ?? thats a huge gap ??

 

if it's dyno dynamics i guess 273 dyno jet 313 good luck

 

What are yall talking about??? He should make @ least 400WHP on 91octane!

 

I would quess right around 300 on a dynojet
