2001 low miles for sale
 

You got a +36 hp gain between an ECU and muffler upgrade? Is that verified on a dyno?

HP question
 

not sure why you think it's +36 HP, the (2.7) starts out at 218 hp, are you thinking the base HP is lower 210? (add +26 ecu tune and muffler) and it's in the neighborhood of 244 correct? almost forgot I added the underdrive pulley for another 5hp? maybe I should have popsted 250?
I posted a link to the muffler and ECU tune on FVD's page, I believe they are legit.

Sorry, I fat fingered the number(iPhone). I meant 26. And I'm not criticizing or starting trouble, just really curious. Is that FVD ECU program good for 15 hp? Is that a realistic figure? Same for the muffler, +11hp?

Your ad says:

the HP/torque gains quoted on FVD's web page are slightly understated, they could be higher but definitely not lower ... I have not put it on a dyno yet but recently I did drive an 04 S anniversary boxster with similar mileage to mine .... I don't know if there was any significant difference in power, low mid or high end.
