hey ho here we go. im back. r33 s1 gtst r34 smic and rb20 actuator, 3 inch cat back exhaust all installed this weekend, car is great as the boost builds up but when its hitting +7 on the standard boost gauge, it boosts fantastically then all of a sudden its like i hit a wall, although im still moving. i don't know what happens after this point because i let off straight away. i did it twice then thought i better ask the boys for help!
