Quite a torquey 4 pot all specs compression stroke completely identical to stock
One build is stock the other with typical bolt on mods
Stock
Big turbo GT3071 21.5psi 3" exhaust bigger intercooler more fuel more timing still on the stock internals
Well done! thats what i call a proper engine tuning, except for the octane and the efficiency part, perhaps you can make the fuel mixture leaner and increase the compression \ advance the ignition timing and get the same hp with better efficiency and more up to date fuel requirements
The 400hp engine in my opinion is… meh 
Thanks !
compression is 9.5:1 im running it on 98 octane as is whats has to be ran from factory here in the EU these cars run quiet rich out the factory think its 11.5 afr on the stock and as low as 10.5 on the big boost 
I didn’t decide to go full bore on the build as trying to keep it on the stock internals but now i will go for a full build now haha
