Yes, I have a dastek unichip Q+ with a raggazon exhaust and now working to fit GTA inlet cams. Without the cams and the exhaust the dyno reading went up from 268Nm to 289Nm at engine and from 176kw at engine to 183.6kw.., I have the dyno sheets so will post them for you to see, only problem is that the gearbox changes to 4th at 6400 and the kw were still rising to if you can get the gearbox to change at say 6800 there will be a significant difference in the power. I don't trust the dyno kw reading, think it's at least 10Kw more, so i'm looking at getting a second opinion, but the pre and post readings were taken on the same dyno, so the difference was about 8Kw and 21Nm over stock.
After fitting the cams a second remap is on the cards, then i will get dyno readings from 2 different dynos and post.
(After remapping though, please note the gearbox goes funny, it changes gears earlier. I think the gearbox can measure the torque or something because it keeps changing slightly earlier than it used to, maybe cos the torque has increased, and upon reaching a said reading, it's computer tells it to change gears... my feeling only, as this is what my 166 is doing. in sport though, its the same.)
Finally, yes you can feel the difference on the road. The pulling is better and harder, and the fuel consumption actually reduced for some odd reason. Maybe the cars are set rich at the factory and the tuner managed to get it to run leaner and more efficiently.. Q+ is the way to go and if you are in the UK they have a dealer. Just do a search on the net..
Cheers
