Well, I'm pretty sure Greg at SZ would have found something else wrong during my tune, but maybe my tune was bad? My boost controller was not acting right back then, (during my tune) but now I have a new one (EBC). I used to tear pavement off when I dumped it b4 my tune and I had cheap ebay turbos and a single intake. Now it starts burning rubber after I get around 3-4k RPM's, but I miss that kick off the line. My Southbend clutch is new and holds tight. I think my larger turbos just take a bit too long to spool up? I have my gain turned up more than my other Z freinds on my EBC, but they all have smaller turbos. My tires are gripping well with new Continental extreme contacts all around.
