Hi guys, ive had my 7 for a week now, and need some advise/help!

1stly the second turbo dosnt hold the boost! It fluctuates (tsch, tsch, tsch instead of a constant tschhhhhh - best way i can descirbe it lol) and sometimes dosnt come on boost at all... ) any ideas? the 1st is fine! Although this occasionally dosnt come on, but this is quite rare.

Secondly, the garge unplugged the boost controller ( a greedy item, fairly old they say) for the fact that it missed with it on. But id like to no how to plug it back in so i can experiment. Their's a female end on it into the engine bay, but i cant figure out where it would plug in, as its a electrial connection. I guessed it would go to the back of the acutators, but i cant find any sockets on these, so im a bit confused.

err and thirdly what should be the standard boost? when i first test drove the car it was set to 1kg, but after they supposedly tuned it, it was set to 0.4kg^cm(2) is this stock? This is a japanese import by the way, incase that alters things, the 255bhp version.

Now, im used to building n/a cars (ive got a 1973 toyota celica bored and stroked etc) so this is my first time on turbos, so i could do with other advise on how to mod etc! Im a pretty practial kinda guy and like to do all the work myself (3rd engine build on the old toyota) So... whats the most practial way of upping the boost safely? Im thinging of getting an Apexi ECU, but am unsure on the first steps to take! Ive just fitted a Blitz twin cone filter which im pretty happy with (hence how im able to descibe the sound of the second turbo lol) so any other help would be most welcome!

Thanks,
Scot
