Hey folks, I recently made a few small changes (3.31's) to my car so I had Ken check my 93 tune. I made 3 dyno pulls, 8, 9, & 10psi, chart listed below.
recap of mods:
Hellion twin 62's, ID1300's, Fore dual pump return style, MPR forged/sleeved long block. I have a 10:1 bottom end so I don't make as much power as an 11:1/stock on same psi. I was on 9-10psi today which was closer to the 680/610#'s. While I still had 93 octane in my car I figured I'd make a few passes at an 8th mile, see how my street setup would perform. I drove 80 miles, aired my 305/35-20 S/S MT's down to 17psi, made 3 passes and drove home.
Here's a vid of my Boost Leash during one of my 10psi passes
As you can see I haven't figured out how to leave with any boost, haha. This was my first trip with a 2step, going to turn it up higher then 2800 next time out. I'm definitely leaving a lot of ET on the table.
For those that don't already know, Bjonnes is the man. I sent him a msg on the way to the dyno, he looked at every log, made some updates before each pull. I did the same today, sent him a msg while on the way to the strip, he looked at my logs, made changes, sent them right back to me while I was waiting in the staging lanes. Just doesn't get any better then that, no other tuner gives that kind of service.
