yea, i guess he was looking at FP’s turbos that night i wont dont he will have a new turbo within a couple weeks to try out
A customer came in for some pulls with a used STI he just bought. He was told the car had 480 whp. After popping the hood we noticed it was a stage 2 catless car and it has an XPT tune on it according to the owner. It’s definitely custom tuned, but we’re not sure if XPT did it.
We did 3 pulls. 216 whp was the peak reading. 
We felt bad, but the car seems to be in decent shape so it’s not a bad buy.
How could you mistake 216 WHP for 480 on a test drive of the car…
A customer came in with an 07 WRX and a common set of mods: turbo back exhaust, STI stock intercooler, STI stock turbo (04-06 VF39), and a Cobb map for these mods on 93 octane.
This is the Cobb map vs. my custom tune:
And my tune vs. a stock 08 STI for comparison:
Here’s a 350z we built. It was stock except for a cat back. We just added the blower kit, pump, injectors, and management. In the future we’ll do test pipes, a smaller blower pulley, and adjust the tune. That should provide a nice gain because the stock cats are rather restrictive, especially at this power level.
Here’s another sleeper Legacy. This was all the injectors and stock clutch could take so the reduction in power caused by the stock cat back wasn’t the end of the world. In the future with those parts upgraded this car will pick up a good amount of power. I’ll be curious to see how long the customer’s ebay turbo lasts as well. We’ve never tuned one on a Subaru before.
The car developed a small header leak on the dyno so we took it off, fixed the leak, and put it back on. I thought I’d post this before/after graph as an example of how a small leak does have a measurable affect on power, spoolup, etc.
Thanks again, Mike.
He said he loved the car again driving back home to Philly.
Awesome. I’m glad to hear it!
I’ve been slacking on posting graphs lately. Sorry about that. Here’s one from today. This is a pretty much stock looking 05 WRX wagon. You’ve been warned. 
Do you feel like switching from a MAFS or whatever it’s called lol (dsm) to speed density(maft) is beneficial other than cleaning up the engine bay?
(1g dsm)
I want to to dyno my car how it is now, and then re-dyno with the maft installed, and new bov
edit: my car has dsmlink
if your meaning a gm maf dont waste your time or money and whats wrong with the 1g bov ? waste of money lol
bump for mercedes numbers.
shhh
I heard a clk 230 made 130 wheel
DSMLink works great with a MAF if there are no intake leaks or turbulence through the MAF or atmosphere vent BOVs etc. If it maxes out there are other MAF options like the 2G stock MAF or Evo MAF that can be used.
Running the DSMLink in speed density mode works well too. PM my why you want to change the BOV.
