ok ive got 20 mins spare so am gonna help you out with this Pete so whether you take my advice or not is up to you fella!
I could haver that car sorted and running as it should be in less than a day (bold statement) im 99% sure i know what the probs are.
My services with this one are a no go however for certain reasons im sure youll understand. I would however get no kicks out of seeing your engine go pop (which i guarantee it will) with the way its currently been de-modded with the setup it now has.
Everyone are on the right lines but still no cherry
So heres what you need to do and unless your capable of doing this work yourself i suggest you take the car to someone who actually knows what they are doing as opposed to a hit n miss merchant.
First off
1)
Cams & timingAssuming these are stock cams as you pointed out, why on earth have they been dialled in to around two and a half times amount of degrees over standard spec fitted to stock sprockets
That is madness.
He does not say as such whether cams have been advanced or retarded but lets assume 'advanced' which will in turn bring valve overlap in earlier which results in increased bottom end power but will make them very mediocre from mid range upwards where car would not acheive your requested TOP END POWER!
Altering the cam timing requires much more than ''il advance it to say **** degrees'' the engine modifications, turbo size and everything regarding the spec needs to be taken into consideration which it clearly was not in your case, and this is the Main reason why your torque has increased yet power / bhp remains the same even though boost pressure has been raised to over 2bar. Even with an approximate figure for degreeing cams it takes best part of a day with taking rc on and off to get the best setting for the car being tuned as no two cars will be the same, everything needs to be taken into consideration and that goes back to the initial engine build.
2)
Boost As some have pointed out..........your boost controller is incorrectly set with the gain-set gain so boost is spiking at above 2 bar then tailing off rather sharply to just above 1.6bar. That is a charachteristic of a boost spike, in other words boost will tail off quickly because it has spiked.
3)
Air fuel ratioPeak power is at around 4500rpm to which afr's are good but move along the chart to 4800rpm then look how afrs leans off hugely......at that point the power also starts to drop yet boost is still fairly stable at around 1.85-1.9bar with torque continuing to rise. The result is an afr chart between 4800-6000 in excess of 12.5 on full boost with torque continuing to climb.
And that is whats going to kill your engine eventually.......The afr line should continue to drop to around low 11s. I would take a bet that your engine is detting like fook above 5000rpm with the given torque
All points toward incorrect cam timing!
Engine speed coupled with Ignition advance & Boost pressure is what increases torque. So boost can be ruled out as a culprit as its clearly tailing off yet torque is still rising with engine speed...........points again to cam timing being out
The map that Abbey did backed up with their graph looks far better in every area.
Torque is in relation to power and a steady yet slight tailing off boost line which is fine.
Max power being 406bhp was acheived at just over 1.7bar not over 2bar with the ropey tune map
So had they raised boost to the same 2 bar what figures would you have seen then i wonder!!!
As someone pointed out, you may need to possibly raise base fuel pressure with injectors you have fitted but i would not do anything until that timing issue is corrected as it will make a big difference to fuelling also
And that concludes my findings even though ive never even looked at your car
If it were me in your boots i would take it back to Abbey Motorsport to sort out, grovel, crawl and say a mate of yours had fooked about with the timing etc and boogered the lot up so could you kindly sort it out lol
