todays dyno antics

[stevmo]

Following my last dyno run where I got 177 and 179 bhp I have since had a full service and cleaned the MAF. This is todays results on same dyno


still got a issue at the top end but I don't really want to spend anything as I want to go back to my mondeo routes and get a ST220 but want to ensure this sells well. Any theories whats up?

BTW only mods to this are pipercross panel filter, NGK irridium plugs (if you call them a mod) and poly upper engine mount

Whats the problem then buddy? its putting more power out than its 177bhp?

look at the top end of the curve - should be a nice smooth line not look like some new kind of roller coaster

Looks like summit breaking down under load

well the dyno operators recon the MAF is at fault however where it surges it induces clutch slip so i'm avoiding top of the rev band (not that I use it really anyway) to maintain my clutch as I dont want the bill for a clutch when I plan to change car
