So yeah this happened: Previously mapped at Darkside with a very different (and pessimistic as suspected) dyno, had some ugly looking boost spikes as well which most likely worked themselves out a bit over time in the ECU: Overall feels much more responsive throughout the rev range with the new map, can definitely tell the power is allot more linear than before, feels much more like a big n/a petrol engine to drive now. Forgot to ask Rick but I'm pretty sure this new map started from a stock 1.9tdi file (probably what all tuners do but I'm a bit lost when it comes to this wizardry) as the map Darkside put on seemed to have some weird alternative gear ratio which was fine in lower rpm but total killer for motorway driving mpg as it was always revving high at 60+ mph in 5th, much happier having that back similar to stock now. I know theirs this whole thing of "dyno dynamics rollers are legit" blah blah but I honestly think Unicorn's were allot more accurate than Darkside's, didn't say what it ran before as I wanted to find out the current dyno figure on these rollers (5bhp more than Darkside's). Totally forgot I'd asked for a popcorn/hardcut rev limiter as well so that was nice to find, was worried when it first (unexpectedly as I forgot I asked for it) hit as I thought I'd broke the car or something haha but now it's just a nice reminder that I need to shift up and hopefully when I get used to the map I won't be hitting it so much. For anyone who hasn't seen previous posts/threads the car is: BV43 turbo, straight pipe, front mount intercooler, EGR delete. This is the 3rd map I've had on the BV43 and each time the car has seemed better and better, won't be getting another one now though obviously as this is spot on, I'm all for getting things done properly once but the other maps were done more out of convenience as I was getting other work done by the people at the same time. Car is definitely capable of upsetting a few others now, turbo seems to kick in sooner and anyone into torque figures knows 360ft-lb is higher than allot of "quick" car's. Many thanks to @Rick @ Unicorn Motor Dev.
