What kind of manufacturer isn't using a temp controlled dyno room? Seems like they would have no way to back up any of their HP gains if they are not running at a standard temperature.

 

good call jeep

and when i was there they had a new camaro on the dyno with the door open... the dyno wasnt in use so im not sure if they closed it or not while testing..

 

I wonder if they changed the temp to make the XD look bad. As in, I wonder if they forced hotter air into it and then forced colder air into theirs?

Or maybe they are right and the XDI does make the truck lose power?

 

every guy i talked to at the company seemed like a real cool dude.. even ken, the guy who did all the negotiating (even is gonna give me an extra filter for the extra day)... they don't seem the shady type...

but anyway... well see what the read outs on the dyno say

 

Does XDI dyno test theirs??

 

Ask for dyno sheets.

 

Like I said somewhere in here.....those make you lose power except theirs of course. Unless you tell your truck that you have that thing you computer throws more gas at more air. So you lose mileage. My 03 Durango 400 bucks later to find out I am getting worse mileage with a cold air intake, and I had that on for quite a while. It made nice sound under the hood. That is what they are good for. JMHO I sold it to a guy in quebec who was afraid to import but would buy everything he wanted thru me. Last thing he ever bought off me, he was pissed he got worse mileage too.

 

No one has a temp controlled chassis dyno. But more often than not the dyno gives SAE corrected numbers to compensate for pressure and temp differences.

 

I would try emailing true flow to see if they have dyno numbers for the xdi on the 09, maybe mention a competitor is testing it and claiming it causes a power loss.
