As some may or may not know, I'm still running the stock IHI. With my mods listed in my sig., I'm not getting full boost (18 psi) until almost 3k. Is this normal or should I be getting full boost sooner. I'm curious what other people are getting full boost at (especially with the IHI). On Stinger's website, I know he listed the IHI getting full boost as early as 1800 rpm with some airflow mods.

I'm still running my IHI and for the first 2 or 3 gears i don't get full boost (17~18psi) until about 3000 rpms. In forth and fifth i can get full boost a little sooner, but not by much, definitely not before about 2700rpm. I don't think my car even starts building boost until after 2000rpm in any gear. Last week i also seen on stingers website that he lists the IHI to get full boost at 1800rpm with some airflow mods, that's why i was testing mine.

You guys seem to be getting about what I got. I was starting to get ready to check for boost leaks. Thanks for the replies.

Goodstuff, how's your ebay turbo working out? I'm thinking about getting one.
