Right, cause that can't be possible with driving that far then dyno'ing immediately after lol.. Did you make the exact same whp/wtq each pull? no. Go drive the car all morning then dyno, Ill be you put down less everywhere and your curve will even look different.

If you would like a fair comparison again, compare my dynojet numbers to yours. Mine were at 22psi spike and I put down almost 15 more whp and 20 more wtq.

 

LOL.. ok there Nick. Look man, he asked a question between HPT and Trifecta. We have a real world comparison to work off of on the SAME dyno and the SAME day between to 2 different tunes so I only thought it was fair to bring it up. That's it man. I'm not here to make some sort of argument out of it. In fact I have always said that both tunes are really damn close. At a track it would really come down to the driver when comparing the 2 tunes against one another. We just happened to have dyno numbers as of now.

 

And Im just saying that isn't exactly fair. Go drive your car a couple hundred miles, slap it on that same dyno, then post the results.

And they do not compare at the track. I havent seen a TF car trap 115+ yet and several HP cars are. Ill gladly let you have a piece if you want to compare LOL! (im not trying to fight with you man, just debating the facts YOU brought up)

 

ok I have a trifecta tune on my car. how can i get it so i can share trifecta and hptuners?

 

You have to order an update from Vince that allows someone to tune with HP over top.

 

oh ok so a retune price and an added charge. so basically he retunes the car, and someone can tune ontop of it with hptuners instead of wiping out his tune? I wonder what my sc setup could do with that combo

 

There would be no reason to do that with a S/C car. There is enough available to tune that car right. The LNF's are lacking WG control, Fuel pressure control, ETC control etc.. All Vince does is set certain options, the actual tune is the HP Tune.

 

i think cmiller went 115 with a 24psi TF tune before you started tuning his car Nick correct?

but he may be the only one.

but comapring traps from diff cars at diff tracks under diff conditions is of no use unless you correct all the times to be fair.

 

oh ok i got you. Should of stuck with your LSJ's I forgot about the tc having limited, but not no more really.

N what would be better for my car you think BYT? HP or trifecta?

 

I haven't really seen what TF S/C cars do to compare honestly. A custom in person tune is always a good bet tho!

Im not sure, hopefully he'll see this and chime in on that one! I know he picked up MPH and .3 off his 1/4 just switching to my tune, and that was a 22psi tune from me using HP alone. So it spikes 22 and holds 20-21 then drops to 17.

 

So your vote is toward HPTuners. gotya lol

 

I'm pretty sure that Vince can update any tables that you suggest him to. If you want the car to run leaner like BYT Vince will do it. Their is nothing on HP tuners that Vince cant do himself. I believe he just lets HP tuners integrate to settle the over all debate. Vince is going to place some updates on my tune to reflect a leaner mixture to see if i get any power differences. I'm logging tonight and I will keep everyone updated with the final results.

 

Vince will not run leaner then .83 on the LNF, even with Meth. I recently asked for a tune for someone for Meth to be at .88 and he wouldnt do it.

 

Not the impression i got. IDK maybe your right. Vince told me he is going to play with my fuel mixtures so we will see.

We can run meth on the LNF now? I thought the Direct injection doesnt allow that?

 

DI doesn't allow E85, not meth.

I just asked Vince about the lambda this week, I can forward you the email where he says he won't run any leaner then .83 if you want.

 

Thanks for the info!

No your fine man i believe what he told you. I will keep you posted what Vince and I discuss. I'm not 100% now so you might be right. He is going to update my car before i go with your tune. I will keep you posted.

So it's not so much that he cant lean it out.. It's that he doesn't want to for reliability issues?

 

Yea, he just doesn't feel safe doing that. He has tested and feels that AFR is best, and that's fine, he's entitled to his own opinion! But he's firm on that AFR.

 

My AFR is at 14.4 when idling on vinces dual tune. GMS1/25psi,My fuel trims are fucked though

 

wow.. hopefully he'll let you play around with a leaner AF a bit. I know he would never let me do a true comparison on the dyno of his usual .82lambda vs an .86lambda the multiple times I've asked him. Let us know how you make out and try to get some dyno numbers of both to compare against.

your idle AF will be very different than WOT. I'd be scared for you if you were running a 14.4af (1.0 lambda) at WOT on a car with any boost.

 

HPtune from 06black. I've had tunes from several different people, and I'd go with none other than him. The others are all good though, and I'd recommend them Bryan is a hard one to get a hold of, but he sure does know exactly what he's doing.

 

Going from 0.84 lambda to 0.88 lambda normally gains 25 whp. GM stage 1 tune runs 14.0 A/F at WT from 2,000-4,500 RPMs.

He is still a lot better with LSJs than LNFs. Helps when you own and tune your own type of car LOL.

 

yeah I would LOVE to get a tune from byran for my LSJ.

 

haha that's right. I forgot they run a crazy commanded .95lambda.

 

It is really hard to tell, I have trapped 107-113 pretty easy on the trifecta, with two passes in the 115 range. I have also been at an average trap of 109-113 with the BYT tune, with two passess at 116 so far this year. I however picked up about 3-4mph average in the eigth with the BYT tune. From 89mph to 93 now.

 

Not really...he's equally good with both. He knows more about these cars than anyone on here lol.
