Don't fall into the numbers game.

Did you do a baseline on it? That's the only way to really tell how that dyno reads.

That's amazing. Would you mind taking data for a few tanks on something like fuelly.com? The electronic mpg meters usually aren't super accurate, so one needs miles and gallons recorded by hand.

All the stock pro tune dynos make their power real early and have that harsh dipoff towards the back 1/4 of the rpm range

Damn, 275/308 is pretty damn good for all stock with a tune.


What was the baseline on that dyno?

That's very awesome to see. I would say the most concerning part of the dyno is the difference in 5400rpm and up. The WRX seems to be having some issues in those RPMs, I wonder if its the compression and lack of octane. :/

Possibly the restrictiveness of the stock intake/exhaust

I'll post up a few, but I will preface this - When posting, if you can, please post an overlay of stock vs. tune of that car on the dyno... or at least what a stock car did on that dyno. This thread doesn't need to turn into yet another thread debating low reading vs. high reading dyno or this or that or all that other garbage that ruins threads like this.

Look at the gains as an overall percentage.

Stock vs. 93 Octane TiC off the shelf AP tune and TiC TGV deletes:



Stock vs. 93 Octane and TiC off the shelf AP tune for Mishimoto intake:
Taken on different days and different cars. Stock is representative.



The links to some of our other charts seem to have gone broken. Let me find out why and I can post up more with various combinations of parts.

Moar,

Would you do the pulleys again, knowing what you know now? SOTP noticeable?

To be honest I didn't feel any difference after installing the lightweight crank and water pulleys. I consider them to be more for engine bay looks than for performance. I now know that replacing the belt is super simple.

JDL Downpipe Uncatted
JDL Resonated Quad Tip Catback
JDL Front Mount Intercooler Kit
JDL VStack intake
JDL Oil Catch Can / Coolant overflow reservoir
Pump 91 octane
Tuning by Delicious Tuning


Bolt on with stock intake untuned vs All bolt ons Tuned


This dyno is known to read 4-5% lower than a dynojet supposedly. I will be putting the car back to stock next week to get a baseline. I'll also be dynoing it on a dynojet with all these mods to compare before we move onto E85.

I'm confused...several of you guys on e85 and not listing injectors? DO the 2015's have ample flow to run e85 on stock injectors and stock fuel pump?

My friend has a 2015 and if he can gain virtually 100hp/tq stock with a tune, I think that's a no brainer!

AFAIK, there are no injectors for the 2015 yet.

I think they are having some issues running E85 full time.

I can confirm that running 100% E85 after several full tanks that the HPFP gets quirky where pressure fluctuates to the point where the engine hesitates on partial throttle. However, I've been running a ratio of 5 gallons E85 to 1 gallon 91 oct without issue. So yes, the stock fuel injectors, tank pump, and HPFP can handle E85 diluted with some petro.

I wonder if this is an issue with the fuel itself and the effects on the HPFP. For example, in a diesel, the switch to ULSD (ultra low sulfur diesel) and it's consequential decrease in lubricity wreaks havoc on the HPFP, even those designed for ULSD. Granted, these pumps are 10x+ the pressure (29k PSI), but same idea. Could a similar thing be happening?
