How'd my local tuner do?

[ltdriser]

Just like the title states. I have attached a data log and the tune. The issue I seem to be having is with just mid rpm grunt. As you can see from the first pull the car does 40-100 in 7.795 seconds and I have plenty of garbage (13.0s) 1/4 times to go with it. I feel like this is very sluggish for a cammed c6 ls2 manual with 425whp. I've ended purchasing the HPTuners to try to learn some things and start correcting ( if there is anything to correct) what my local tuner did. Take a look and let me know what you think. I'm particularly interested in knowing what hes doing in the PE section. It seems to differ from all the reference tunes I've looked at.

It's not a bad tune. It's a little different than I would have done, and might could benefit from a couple more degrees of timing down low...but it's not so bad.
It goes into PE mode pretty quickly when you went WOT.
What's your 60' times and mph through the quarter? Was it a dyno tune or a street tune?

[ltdriser]

It was a Dyno tune 425whp/381rtq.

[ltdriser]

Ive ran 12.9 @114.8 with at 2.18 60' and 5.8 330' on street tires. Which just seems slow compared to what the Dyno is telling me.

[Lakegoat]

That 2.18 60 ft is killing you.

Tune looks perfectly fine, not going to get much more timing in LS2 at least on the gas we have around here. Fuel trims arent wacked

Narrowbands look ok. If its lacking midrange grunt its probably in the cam choice. I can tell you even if it was a happy dyno and its really only making 400 then problem is driving and not the tune, hate to break it to ya. 360hp in a TA that weighs 500 lb more I would trap 115 in decent air

Change your PE Delay to 0 rpm

Your intake is restrictive. 10-20 hp worth (manifold vacuum at WOT)

[Xjas]

Do you have any data logs of your quarter mile runs? Or data logs with a wideband?
What are the cam specs? Judging by your idle speed and manifold vacuum its a pretty serious cam, that's probably what's knocking out the mid range power and making it hard to run good times at the track.
I agree with GrannySShifting, your dyno sounds a little happy, I've run 117mph in a 3800lb VE SS M6 (Think Pontiac G8) with 411rwhp.

A little update, I managed a 12.59 et at 115.77 with a 2.05 60' on street tires. 1950 DA
Cam is a 231/242 .617"/.592" 112+2. BTR Stage III.
So with the Dyno sounding generous, what gives? LS2 with cam, vararam, headers, exhaust, and tune. Wouldn't ~400rwhp be low for that setup, they're 400bhp from the factory? Corvetteforum seems to be chock full of guys with similar mods in the ~440whp range. This was my first build so I am always looking for pointers as to why mine may not be where it should, if it should be there.

Trap speed seems real low. I have a 2000 FRC, LS1, 243's and a smaller cam and trap 122.

[Srblacks13]

Oh, and the dyno said 417whp. Hard to believe dyno numbers, but trap don't lie.

Since you have a manual trans, you are going to be slower than an auto car. You need to get some slicks and get that 60' down to a 1.5. It will reduce your et about a second.
