'09 370z Tuned with EcuTek by Ptuning with numbers

Mozen

I finally got my car tuned right at Ptuning and with the following mods, (most of the kit from Z1) i love how it drives.

For power I have NST pullies, Ported Intake Mani, Stillen Headers, Berk HFCs, Motordyne Cat Back Exhaust, Stillen Gen III Cold Air Intake. Driveline is a Spec Stage 2+ Clutch w/Steel flywheel and a Quaife Diff with 4.08 Gears.

The date is off on the sheet but this was done yesterday at Ptuning. There is no wonky calibration factor or any of that stuff.

Staff is exceptionally friendly, tuner was knowledgeable and on the ball and after talking to me for a while about what i wanted to do with the car and the direction i wanted to go offered some options.

I did not as there was no real point other than to discredit my etuner. (not ptuning or Visconti ) I have had most of the mods over the years slowly added as i had time/money.

Probably no more than 10-15whp Max from my experience with other cars

that would put the car at or close to 350rwhp... thats exciting

Yeah it would but remember every car is different and with NA it's harder to make horsepower because the motor has to get the air in and out faster on its own vs with boost or nitrous which is assisting the motor a lot

swapping LTH's for stillen headers/HFCs wont gain you 10-15hp. maybe 5hp at best due to dropping the HFCs

if it was stock headers/cats and you swapped for LTH's maybe.

I disgree, i can see 10rwhp...a proper LTH will always make more power than a shorty anyday, berk HFC are still 300 cell count cats, that plus retuning....i can see about 10

Depending..... I can agree most people see 5-8 but I have experienced personally gain 11whp from swapping from hfc to long tube tune plays a good part as well. just sharing my experience

just adding parts to an already modded vehicle does not net you the power the product itself is advertised for when being added to a stock setup.

basically diminishing HP returns the more parts you add. removing the HFCs will be the main reason of gains taking some restriction away.

i know how dimished returns work, imo 10 more rwhp swapping the stillen and berk hfc for a lth and retune isnt far fetched. Ive seen lth consistently through out the years yield more power than any shorty. Say you get 5 from going from 300cc HFC to nothing, 2-3 from the lth and another 2-3 from a retune. I could see that...

I don't think even 5. Idk the stock headers are high flowing as it is, the stillen I have are not much better imo. The cats I have are Berks but have heavy use. I think lth at this point might be 2-4hp with everything else.

Also the dynotronics is known to be low numbers which is why I like it because even tho its low its dam sure accurate if low.
