well since I was down doing a ROM dump to switch over to ECUTEK I decided to do a quick dyno..
First dyno on gears and wow I was surprised..i didn't know that the load rate on the new gears was so different compared to stock..here are my new base numbers on the 4.08 gears

Have a pic of your old dyno and is this with your new plenum also?

Noticed with ECUTEK that the numbers were the almost the same every pull. My uprev baseline looked the same big variance between the first and last pull.

here is my original dyno just as I got tuned..
And yes this is with my ported plenum. I was talking to Seb about why it's so different and he says gear change the load on the dyno.. We tried a 5th gear run as well and same results..I'm not disappointed at all because I know the car is faster with the gears.
I guess to find out now is I need to go to the track and get some 1/4 mile times.. I picked up my ECUTEK cable but won't switch over till October..
