Yeah I remember you going away from SD to tune the transmission but Seb was able to get my transmission perfect using SD. It is a lot easier to tune on SD. I couldn't be happier with his tune. If it doesn't go good on the dyno for you I feel it is the tuner and not the car.

Im starting to think this is the case.

I have always questioned it. He's tuned some monster turbo GTRs around here, one is over 1,000whp but I question how well he knows superchargers. We may never find out if they don't run the car today.

The not making boost was clearly the car but that should be fixed now.

how did you SD tune it? what sensors did you use and how did you do it!

I want to know this lol..

fill me in brother!

pics of your set up?!?!

The thing that has made me question the shop this whole time is how much you've had to do to find the answers to provide for him. If he's that good, shouldn't he be the one finding solutions, not making the customer do it?

I couldn't agree more! The other day I was screaming that the car had been there 6 months and he had the nerve to tell me " well this was a lot harder than I thought it would be!". I lost it on him and said " MFer if I had not done all the research, worked on the car myself and came here every day so you can't blow me off this would be a two year project. " When this is over I'm done with them if not before its done. He must only have knowledge on GTRs, people send this shop GTRs from all over.

Sebs sent me a Haltech 3BAR map sensor with an in-line filter. I just had to unplug the MAP sensor on the back of the manifold and plug it into the Haltech. The vac line t's into the vac hose off of the front of the manifold. Did not have to modify any of my sensors or run additional wiring at all. Seb did the rest. lol

A few more pics.

There has been an awakening, have you felt it! Sorry I'm a huge Star Wars fan. The car just made more power that it ever has by 1whp. It's pig rich and he's not positive where the boost was. He thinks 8 but said he was watching the AFR close. As tight as I have that belt it got hot, I think it's still slipping.

Heyyyyyyy thats good news!! :happydance:

It's still pig rich but they are working on that. I don't see how it's slipping unless it's flexing at the top end.

Yeah def really rich. Those are impressive numbers so far with as rich as it is and not going to redline.

Wait. WTH? Why are your lines crossing at 6500? First time i have ever seen that!

And its Off The Charts rich! Literally.

It would be great to see your boost values.

Because we didn't know where the slipping started I had then add a lot of fuel, I didn't want it going lean.

I thought the same thing, I don't know why.

Thats mathmatically impossible to cross up there. Something is not correct. Settings or something are off. You might be making bigger numbers than what is displayed.

Is the tuner letting off the throttle by watching the screen or the RPM gauge? Are you there? Look at it next pull.

I'm not there.

mine cross over at 5800, but it was crazy lean.

Oh wait. If you draw a line across from the torque at 5252 it is 325 and if you do the same with the HP it is also 325. He is just displaying it on there differently.

Nevermind.....

It should always cross at 5252 unless the units are not hp (for power) or lb-ft (for torque), or there is some odd correction somewhere.

Aha! Nice work, detective. Now go find Carmen San Diego!

willis you gained some torque didn't you?!?!

I gained about 45 more wheel torque, I was amazed, same dyno, same tuner.

Already bought her a beer....

Yeah. What were your numbers before going into this?

Before 418/311.

30 wheel torque is really good!

I bet youll see 45-50 over your previous set up once he leans it out a bit!

I cant wait to see the finished results, You deserve them!

The numbers are scaled differently on the left and right side of the graph, one side represents HP, the other side represents TQ... I hate it when they do that.

I can't believe they are running the car on the dyno without a boost plot. That would solve all these questions about the belt slipping. Or even looking at the boost gauge in the car and telling you what it read. You shouldn't still be in the dark about that simple reading. I don't know man, with this amount of time and investment in the car so far, I'd vote you the most patient man on the planet.

I'm next to positive my other tuner could log this, do you know how its done?

It's a tap with a t off your minifold or bpv.

That seems easy.

Wow.....Congrats man.....I can only imagine how much more potential there is when ur making those numbers running "Richer than Richie Rich!" Ur AFR is going way into the 9 ' s zone which made me sputter when I was on a rich tune from Stillen....I couldn't get over 3K on the RPM band without my plugs getting drowned out. ...It's a good thing though that ur making more power and TQ on ur first trial run....

In regards to ur belt slipping....is this with ur COG setup?

Still only 9 psi.

No the cog isn't on it.

hope it all gets finished for you today mate!

We are talking about using the cog set up, I need to look at the numbers tomorrow when I'm sober.

That dyno plot doesn't look too bad. It's dipping rich for sure, but it goes back to normal by 6,500. So your upper range power numbers are there. Do you know how much timing they have in the tune? My guess is that they're still in "safe mode" and just trying to stabilize the AFRs before they start pushing the timing. Now if you're low on boost, then that's a different story.

Back when you ha a healthy tune, and were running 9psi, you were at 418whp? So, so far, you've gained ~17whp on the same amount of boost. I'd consider that in line with the better intercooler and headers. Now if you can figure out how to raise the boost, you should start seeing some healthy gains. If the car has fuel to spare, and is healthy and happy at this 9psi, I'd guess you'd be seeing closer to 500whp at 11-12psi.

The rich dip isn't killing the numbers, it's just too rich in the middle. You might be leaving some 'area under the curve' on the table, but it comes back at the top. Your torque curve stays flat when it goes rich, so it's not choking itself out.
