I have not tried on the road yet but reports so far indicate it's works very well , the car is with Bob so he could say how it is on the road , I have not seen anyone else using this unit but it looks good so far
Was just about to post a reply regarding your turbo Allen but you beat me to it lol.
Btw welcome to our forum
As said i have just mapped the car at a very safe level after carrying out engine swap and other modifications so will up the boost at a later date.
Our resident mapper 'Terry Dolphin' checked the map I did and said it was pretty much spot on with scope for more power at the given 1bar by adding a bit more ignition it could have seen high 340s with good torque also (im just playing on safe side for time being). So quite a compliment from the legendary Mr Dolphin who's teaching me more every time he is here and really getting the knack of this mapping now but still lots to learn.
Took car on a test drive yesterday and must say im very impressed. ive driven many cars with 2871r tubby's over the years' but this thing pulls so hard and comes on boost early with next to no lag. I capped rev limit to 7200 for time being until other small issues are resolved but when it comes back for the final big power map Im intrigued to see what this car will make at 2 bar boost as I have no idea but the results so far are very promising and AET who custom spec'd this turbo are not giving any figures but I reckon it will knock the gt2871r into tomorrow with its overall power and the speed it spools too
spec:
Aet's own custom turbo(modified from 2871r)
z32 maf, 800cc injectors, fmic, quaife g'box (water/meth injection to be added), mapped on Apexi power fc
previously mapped by last uuum! well known tuner at same 1bar boost (same turbo) car made just over 300bhp at SRR prior to engine saying night nights after severe borewash.
I did 1 run on our dyno with the same map prior to wiping it and starting afresh, she made 306.8bhp but was severerly overfuelling which was very apparent as ex fumes were eye watering
So in answer to your question Colin deffo worth a word with Aet regarding their custom gtx spec tubbys
