1) I call BS on the 1000rpm increase in spoolup

2) This guy can't speak proper English, "recommand this mods" ?

3) Theres no reason why changing the exhaust manifold and the 02 housing would allow the car to pull hard to redline without changing the boost control.

When I put in the Helix HF cat the car pulled harder and the turbo seemed to spool quicker hitting max boost faster than before.

Perhaps English is not his primary language. No need to be harsh. Its not like we are in the Spelling Bee contest here. So what if he mis-spelled the word "recommend"? As long as we understand what he is trying to say and thats all it matters.

overall the quality is pretty good, but my mechanic having problem putting on the 02 sensor into the housing. He mentioned the thread on the o2 housing wasn't that good.

god you guys, forgot about my comment number 2 and focus on the others. Does anyone see anything wrong with 1000rpm quicker spooling time?

Dave2, how exactly did you measure this increase in spool? by a boost gauge? on a dyno? just by a feel?

.... stock turbo spools up at what rpm range? thought it starts spooling when you step on the gas. It will hit full boost at between 4k-4.5k depending on mods and then tapers back down. Thats why an accurate boost gauge is very important.
