Well, i had to laugh
Made a start stripping the 3dr today, and upon removing the rollers and taking the plenum off, i found that not only did the engine make 397bbhp and 386lbft....
it also done it at only 3/4 throttle
now, i know that when i fitted them i was getting full throttle etc, so can only think that when it was being mapped the max throttle stop screw was adjusted, instead of the closed throttle stop to adjust the idle lol.
so, what difference would full throttle have made to the overall HP output? im guessing a fair difference as it would have moved a LOT more air.

another 100bhp possibly fudgey

doesnt that give you the incentive to fit it into something else then get it remapped again to its full potential to see what it makes? i know you had a raw deal with them pikeys crashing into it, every cloud and that

who did the mapping?

nope, not yet! hence breaking. as i signed the paperwrok accepting the offer, so borrowed a lot of money of my dad to buy a new family car as ours was fucked... then they said the other ins co are witholding the cheque as the other driver has not admitted fault...
Given the size of the barells (45mm IIRC) I would imagine that 3/4 throttle was still enough for them not to be the bottleneck in the system anymore (ie they probably flow more readily at 3/4 throttle than the head does for example), so I suspect little or not difference between a run at 3/4 throttle and full throttle for your application.
the throttle cable? i did, but at the time of it going to EP there was NO throttle stop on the pedal!

Testing the future
can't you tell what the throtle position is from the mapping software? imo, your mapper should have checked this before they even started 'twiddling the knobs'

PassionFord Post Whore!!
as above, thats just what i was thinking.
surely the TPS wouldnt have read fully open and been a giveaway.
i know when i bought the IAW monitor for my L8 ecu, it showed i wasnt getting full throttle at the tps, that lead me to find out that my throttle was jamming at 7/8 open through a mechanicle fault ( lever on the side was bent and getting stuck against itself lol)
if i can find that out surely its more obvious to a tuner. lol

Crikey - if we'd had another 25% throttle we might have sat wheelspinning at the exit of the MOT station for 5-10 seconds and pulled out BEHIND a transit connect van...

When they first started mapping the car I would have expected them to calibrate the TPS as one of the first things they did, and at that point fudgey is saying it was still working properly so would have had full travel, so when they set the 0% and 100% points that would have been correct, so it should then have been obvious to them at the end of the session if going full throttle in the car now only gave 80% or whatever on the TPS.
But that said, if you are working Speed/Density which they would have been, you arent looking at the throttle with anything like the closeness that you are on an N/A car so its probably easier to miss than you would think.
All a bit acedemic now as its not like they can do anything about it anyway of course.
