For the most part I am, but I'm concerned about the torque curve and why it goes up and down instead of holding constant. The dyno shop showed me some other car's charts, and how they held constant. Perhaps like was said, maybe a boost controller will help even it out.

Your numbers look really good for your setup. The HP and Torque look on the money. I would be very happy with those numbers.

Looks good, that's also one of those dynoes that measures at the axles rather than the wheels though?

My only concern with the 19T is getting a tune for it. With the 18T I can get the IPD tune, but guess I could use the IPD 18T tune for the 19T.

Im running my 19t on a 15g stage 2 InMotion tune that costed me 250$

My AF/R ares in the 11-11.8 at WOT and in boost and not WOT im at 10.2-10.8


so theres nothing wrong with running a dif tune, just loosen your wastegate...and grab an EBC or IPD HD TCV...stock BCS is really bad...especially on cars over 100k

I prefer my HKS EVC IV EBC, that solenoid is like a tank!

The numbers look great man...

I would just get an EBC, dont waste your time with a MBC. Dont get me wrong the MBC is an improvement over stock controller but judghing by your setup i would guess you haven't skimped or cut any corners, then i would ask why do that now. You can get an MBC from $20 (or less) to $100 (so say average of around $50 - $60), an EBC average cost is around $300. U know how they say you get what you pay for... well it applies the most in this case.

I had an MBC and it was an improvement over stock controller, upgraded to EBC and it is as substantial an improvement if not greater.

I think that will control your peaks and valleys a little better, and if the dyno guys give you a copy of your A/F readings post them up here as long as they're plotted against RPM.

[Snabb T5M]

ok, here's all 3 charts together. As for the EBC, think its going to be the HKS EVC V so I can dial the boost into either speed/RPM or throttle position.

WOW nice HP # for a 16T! IMO with a built engine why bother spending the money on the pop can 18T/19T that you have to run the $hit out of them to get 300whp. If i decide to pop new rods in over the winter, i will not be running an 18T any more. A bigger Turbo and the Turbo Tuner is your best bet unless you just want a bolt-on/generic tune, and call it a day. Theres all sorts of HP not being used with these off the shelf tunes... there not dialed in like a proper custom tune. But it all depends on what your needs are?

[socal850tuner]

AFR's look fine... with your current setup everything looks fine in my opnion

[Snabb T5M]

Yes, the dyno was hooked straight to the axles with the wheels removed.

[ryan850-t5]

I'm not sure why people spend all this time rebuilding an engine and they only use an off the shelf tune and a 19t. Go get turbo tuner and a garret turbo. Then you can really dial it in and get the most efficiency out of the setup. You spent time on the build, now spend a little extra time and get it running right.

nice numbers btw with the 16t though.

[Snabb T5M]

And where does one buy the Turbo Tuner in the states? I could buy it and take it to the speed shop for tuning since I have no idea what I'm doing.

http://www.turbo-tun...hoppingcart.htm Click on the North America distributer and you can find out all. The Vendor(Turbotuner) is also a VS member. Lookforjoe i think? is waiting for his TT to arrive. Hey has a Hahn 20G.

What plugs and Plug gap?

AFRS and numbers look good, but that wavy torque curve is commonly a telltale sign of weak spark.

If so, it has some more power left on the table yet, crazily enough.

[Snabb T5M]

OEM coppers, gapped to .028 I think, whatever factory gaps are. Plugs only have like 5k miles on it since the motor rebuild. I have the MSD coil. Think I've decided to get the Turbosmart Eboost2 boost controller instead of the HKS one. So hard trying to decide which one.

280+ WHP is pretty respectable for FWD using a 16T!

Yeah, I'm waiting - there has been a delay in ME4.4 release.... ME4.3 for 850's has been out for some time.

The tune is very important I've been limited to 282WHP with the tune I had, as it just leans out too much over 17psi on the 20g. I have a revised tune comingfrom Sweden that will use the 625cc Siemens, and scaled for the 20g's CFM rating - to allow boost in the 22+psi range. I'm using a stock T5 ecu, running 15psi in the mean time.

If they can print out the line-by-line, it's easier to read - and yes, I KNOW this was over lean

I have to ask if this is truly representative of True/ Wheel Horsepower?

The reason i ask is there are losses from the tires alone, and since you aren't factoring that in, with them being removed. I am just wondering as I am aware of the roller type dynos (regardless of make, mustang, etc), they actually measure horsepower at the wheels, but a dyno that measures at the axles would give you slightly embellished numbers, unless it calculates or corrects the numbers with correction factors, dyno-software, etc???

Just asking, simply because i am not sure or not knowledgeable, not trying to stir anything up, just wondering?

[Snabb T5M]

Here'a link to the speedshop and a discussion regarding their dyno.

Have you ever seen a TT car that was actually tuned with TT? If so please pm me so I can talk to them. JCViggin's tune was done by MTE and then copied to TT. I can't find a single person who has bought TT, tuned their car, then posted the numbers.

His tune is based of of his MTE tune. He said himself he couldnt imagine not having control over his tuning, and loves the TT.

That is what I just wrote. I realize he likes being able to adjust his map. But....

Has anyone started with TT alone and had any documented results? Not based off any other tune, just built motor, larger turbo and TT tuned with notable results.

Please fill me in. There seems to be a lack of this scenario.


To the OP, why does the dyno say 4wd?
