I bet with a decent cold air, a downpipe and the SC tune - I will be damn close to 300rwhp.

 

Maybe, depends on the dyno and correction. Knowing what the airloads are set at makes me very skeptical that it can make that much HP as the HP drops off really hard at 5500 or so.

 

HP drops off really hard at 5500 because the stock air intake is a known hinderance to performance.

 

It did with his Hahn intake on there. It drops off because the airloads are not much higher than stock up top.

 

Dave... it's not worth the hassle... some just don't get it!

 

I wish everyone could see and understand what is really happening instead of throwing out pure conjecture.

 

Put both of your pretty-ass numbers on a drag strip, then I will get it.

Real world performance on the STREET (track) is where tunes shine the most.

Believe me, as an ex 2003 Mustang Cobra owner there were many, many dyno queens that bragged about their monstrous numbers constantly. Where did that get them? Beaten by better drivers with less $$$ invested in their cars and workable cars that ran on the street.

It's sure nice to say you have 350+hp, but is it usable? A stock tuned car will start pulling you if all you are doing is roasting the tires...

But to each their own I guess.

 

So is the power drop off is on all cars or is it just in this case. So an aftermarket cold air is hindered by the engine intake?

 

If you number driven then fine.... the rest of us just enjoy having the power on tap if needed... Numbers are Numbers...

12 second cars can take a 10 second car in certain instances...

I use the dyno to hone my skills, and see what improvements my tunes make! I could care less what it does on the track... If it runs great on the street that is the most important because my car spends 99% of its time drivng me to and from work and what not!

Dyno's are tools... and the only part of track time I care about is trap which once again just shows true power... My car has been to the track, but who cares!

The power drop off is there because the turbo runs out of flow... the only way to change that is to change how the car see's the air loads..

You can trick the car into thinking it's only moving 19psi when in actuality it's moving 22-23psi.

I have changed those on my car so it see's a constant 245-240 Kpa throughout the entire powerband!

 

is that how they got the 20 or 21 psi boost to work on the LNF kit since it claims that high or do the new sensors play a part in that?

 

Nah the 20-21 psi is the most effective range for the turbo... commanding it to boost that much really early causes it to drop quickly up top.

What we have done is make it comand say 22 psi in the midrange and then command 25ish psi up top because we know it's not going to flow much over 23 psi for long periods..

basically tricking the MAP sensor

 

So, how difficult is it to learn to tune? What types of software, etc, do you need? I've always been a do-it-yourselfer, and as much as I really don't want to void my warranty, someday I'd like to learn how to tune my own car. How did you all learn to tune?

 

So what did ya run?

 

We turn up the airloads and max airload torque table to increase the pressure level at which the ECM tells the wastegate to open and we command more than 23psi up top so the turbo does not run out of steam so quickly and flow and pressure stay up.

 

It's not hard... it's just making sure you know what the numbers you are changing are and what they corelate to.

That is what took me the longest to figure out, but I had a damn good teacher! ***PROPS TO AREA47 GO HERE***

ON the LNF I just started with a base tune and took it from there... finding the happy median and then going past that to find the point where the car gets pissed off!

 

Nice!! Can't wait till I get HP tuners. Gonna practice on my camaro before sourceing a spare ECU for the Balt and digging into it. Learning to tune on a non-boosted engine is much safer anyways. Problem is I have a 10/100k B2B warrnty on this thing so i will probably go with the LNF kit when it "never" comes out to ride that out. Then its on like donkey kong. Hopefully the learn feature with the new GM tune is effective enough to make slight adjustments for exhaust modification.

 

LS1's are a PITA in their own ways... ha ha ha good luck though... don't hessitate to ask for help.

There are plenty of people on here that are willing to help out, as long as it doesn't get out of hand! ha ha ha

 

Ive been involved in enough Clubs/Boards to know how easily things can get out of hand. Kind of like the Cobalt Type-S from Flordia. People always have their opinions.

 

Yeah, there are plenty of ways to screw **** up... ha ha ha

 

Here's something. My car sometimes has an issue going into 1st and reverse. Its not all the time but has been that way since I bought it. It only has 1500 miles on it so I know its not wear and tear. Is this common in the LNF cars? Also are the 4 doors more prone to chassi flex?

 

So what did ya run?

 

Thats pretty normal actually my LSJ car did that too.... Just run it through all the gears it usually opens up the reverse lockout gate that way....

 

Thats what i do. My T-56 in the camaro does that too. Maybe its that GM trademark the British always complain about in american cars.

 

most likely lol

 

Wow - still no timeslips from the "super tuners".

Why am I not surprised?
