Dyno'd the Harley today 427rwhp/....

so i went to GM Express Racing and got it on the dynoe the truck is a 2006 f250 ccsb harley 4x4 , truck has the following corsa catback,cat delete,190s from industrial,and tunes from innovative , i still have the factory airbox with the factory old filter,factory downpipe .....yes it is studded and deleted
first run was 427rwhp they said something about not knowing how to get the torque reading on these truck so i was kind of dissapointed
second run we let it cool down a little and it did 422rwhp and again no torque ... does this seem about right or is it kind of low?? i think its preety good considering ive only got a cat back and injecters tuned..

Agree that the number is low. I put down close to that on just a SCT, exhaust, and intake.

I see you have the factory air box, maybe the filter is not flowing enough air?

Factory air box is good to 500 hp.

Was this a dyno tune, or a tune that IDP sent and you threw on the dyno?

Are you running a stock turbo?

Wait. Had another thought. Was there a load on the dyno to get the turbo to spool / hold the truck in gear? A 10% load on the dyno would bring you up to 470ish and a 15% load would bring you up around 500 hp.

Have you had the truck down the drag strip?
