White = lean. You should have installed new plugs before the dyno session. Probably would have gotten 2-3hp more.

 

Also, check the gap on your plugs. Too small a gap and the spark won't be large enough to burn all the fuel. Too large a gap and spark can be blown out(although I highly doubt this is the case with yours as 6-7 psi is not much).

 

Peter rocks!

 

thanks Peter for hosting this fun event (untill the drive home,I almost wrecked twice)! Me and my friends had alot of fun. Joes jetta gli put out alot more than we thought it would which was very cool. now all he needs is plugs and he said hes coming back to you for a tune with VACOM. I also couldnt belive how good my friends 350z did (255whp) with stock axle back exhaust. i will deff. dyno my S next time one of these meets are set up. i had old oil this time and dont like to push it hard when the oil is around 3000k miles. once again thanks alot and we had alot of fun. ISP deff. won over a few new customers with us. nice meeting all you s2k guys and hope to see u soon.

 

Thanks Peter for hosting S2ki for a Dyno day. I will try to make it up there sometime soon to talk to you about the EMS maybe we can fix the lean issues I am having.

Here are the graphs guys

Joe's vw graph

 

thanks guys. I would like to see how much power we can get out of super charged motor when it is properly tuned. S2000s like leaner a/f than other cars but 14-15 a/f in my opinion is dangerous.

those numbers look about right to me. stock boost?

 

it was running 7 pounds. since it was running very lean it might of knocked couple times. if we can get knock count down im sure it will make couple more ponies.

Peter, thank you SO much for putting up the modified dyno sheets. These are much more helpful. The only complaint I have is that you got rid of my 522lb.ft of torque. You robbed me!

Thanks for being so responsive.
