Not So Good Rolling Road Result

Not too bad power Al. The AF ratio is about what I would expect (guessed) your car to be running.It will read richer on the RR than on the road so always allow a bit for that. the other thing is you need to run the GTT adjustable regulator with those injectors. It does 2 things (1) allows you lean it out a bit and (2) allows the fuel pressure delta over manifold pressure to stay constant . Your boost does seem a bit low for a 17% pulley +GRS ...I would expect 18psi.
Shrick cam likes a bit of fuel. Did you ever get back to the garage who did the work (head &cam) or did you give up on them.
Id like to see' low to mid 11's ' on the RR.

The power is fine high up - the car just has nothing below 3000rpm which is "normal day to day" driving. After being a passenger in Mart's car I realised what I probably should be achieving - as I've said in a previous post "chalk & cheese"!!

I haven't given up on the idea of the AFPR yet. I also haven't given up on the guys that fitted the head & cam for me either - the only problem I have is that the distance issue as it means I have to take time off work...............no work - no pay so it's a double whammy!!

I've attached last nights RR charts.

Cheers,
