Dyno run questions

[jonnyz16]

I put a Dinan chip and exhaust on my 318is and then found an add for dyno testing so I went down . It only ran a 125 hp and 114 torque . I guess the 150 Hp number on Dinans website must be from the crank ...What is my crank hp if my rwhp is 125 ?

How much does the drivetrain takeaway ?? I do feel a noticeable gain and alot more exhaust note but 125 hp seems alittle low doesn't it ..

Mods as of today on the 318is are : Dinan chip, Dinan Exhaust w/o cat conv. and a stock replacement K&N air filter..

add about 12-15% .

I agree with Vance, differences as much as 20% not unheard of. I would look into a CAI to help that eng breath better after taking care of the exhaust. K&N is OK, but your still breathing in hot air from under the hood. [bmwkick]
