Good news at last lads!!
Took my 9 back to Henry on Tue past to find out why the heck my bhp was down at 173!
he phoned me back 3 hours later to tell me that it was the way my DC2 airbox was set up, my 63mm cold airfeed to it was WAY too small! I was so glad it was something simple so he went ahead and adjusted the tapets, checked the spark plug gaps, put it on the diagnostics, etc, fitted a brand new Top Fuel carbon fibre induction kit that I got courtesy of Funky Power and put it on the dyno and it made a sweet 193bhp!!
I was over the moon!!
I just told him to go ahead and tune it while it was there so he phoned me the next day and said it was all tuned using a P30 ecu with full knock board using crome! It made 206bhp and 133lb ft torque!! I was absolutly shocked as I didnt know those figures were capable from a B16B with stock internals! Picked it up today and to say its fast is an understatement!!! It pulls hard as **** in vtec from 5.1k right up to 9.2k!!! I have 25whp extra in the midrange! it drives amazing, is so responsive and sounds immense!
Sorry the picture is poor. you can see the top 2 lines are the 193bhp run and the bottom lines are after it was tuned!
Thank you to everyone who gave me help and opinions! I am glad its all sorted and I can enjoy my 9 again! Henry is the man! If anyone wants his details let me know!
it just shows how important your airbox/airfilter/cold air feed is so investigate before you fit something!
