Car is a 2006 S40 T5 AWD with ~103k miles on it. Just bought a couple of weeks ago from a former SwedeSpeed member. (He went full Ford and has a 2015 Mustang GT now.) Well maintained, all the little stuff already taken care of.
He did the following performance mods:
3" EST downpipe
DO88 intercooler (full kit, big pipes all around)
Magnaflow cat-back exhaust
Larger intake tube and a pod style filter (a downgrade from stock airbox, I know)
He then got a Hilton stage 2.5 tune. I have DICE and the tune files.
Just went to one of two local shops with 4 wheel dynos, paid for 3 pulls. Nice guys, seemed to know what they were doing.
Here is the graph:
Rounding, 231hp, 277lb-ft at the wheels.
This is on a Mustang (150?) 4 wheel dyno.
Is the car not making power like it should, or am I just expecting too much? I somehow got it in my head it should be making around 300hp at the crank (Am I? Is Haldex that lossy?) but now I can't seem to find anyone pulling those numbers with a similar setup. In fact... I haven't found a single P1 (S40/C30/V50) Hilton 2.5 dyno graph. Maybe I'm just bad at searches.
Are my expectations unreasonable? Is there something wrong with the car? Something wrong with the tune? I was really gung-ho to keep building this engine, but starting with far less power than I thought it had has me hesitant. Expectation bias.
Haven't reached out to Hilton yet. I like how the car drives and had planned to go to a K16 and bigger injectors in the near future, intending to go back to Hilton for the upgraded tune. Now (perhaps unfairly) I'm wondering if I should go to Contrast or that guy on Instagram everyone is crazy about lately instead. That of course assuming it's worth bothering with in the first place.
Please, share your experience and suggestions, I'm feeling more than a little lost. Thanks.
