B18C Not making power it should

Recommended Posts

Hi all recently tuned a customers car, setup is

B18C Stock block
Brian Crower cam gears dialed +1in and -1 ex
68mm throttle body
ITR intake mani
Custom header 2.5inch collector and full custom 2.75inch exhaust 

Using LINK ECU G4+

AFR at 12.8:1 At 8500rpm

Made only 201ps where stock comes 200ps..
550cc injectors and run them at 49% made the calculations and shows 230hp.

Any input on why it doesnt make at least 220-230?

I check a couple of cams and the spec of those cams, they look "small". I havent tune a B series with those cams, it would be interesting to see a dyno overlay with the stock cam and with that cam to see if it gaing in midrange atleast. you have the Vtec activation at 5400rpm?

Yes vtec was set at 5400rpm.Tried 6000 makes a big dip. Tried lower than 5400 nothing really changes. 

Found a problem with the cam gears i will retune and post it.
