Made some dyno runs today
I put down 279hp at 5200 rpms and 313 tq at 4200 rpms. I found out my car runs rediculously lean up top. Check out my A/F Ratio.
These were done on a Dyno Jet.

Dyno run #2... 270hp/308tq

Dyno run #3... 279hp/313tq
http://s4.photobucket.com/albums/y12...t=100_0687.flv
Watch how high my A/F ratio climbs in the upper RPMs...
RPMs MPH HP A/F Ratio
I am going to change to a colder plug to try and compensate for the lean conditions. Considering how lean it is, I bet I could run some race fuel and knock off a few 1/10ths of a second.

I am BROKE dammit!!!!!
Im looking into someone that can reflash the chip. I met him and he told me that he does laptop tuning, mainly with Diablosport. The dyno guy specializes in SCT, and I have a Diablosport chip. I goit dynoed for free bc I know the guy. op No, my motor isnt stock. I've got AFR heads, E-303 cam, Edelbrock Performer 5.0 (original), and all the other usual boltons. Its on a 150k mile bottom endthough.[&:]

RE: Made some dyno runs today
It still the 19s. I have the MAF for 24s, I just need some more money so I can get the injectors. I took off the Granatelli MAF I had on there to sell it and put the stock back on for now.
I freaked out when I saw the A/F ratio. I couldnt imagine why it was running so lean, and then I remembered......
The car was dyno tuned with the stock MAF sensor, JBA shorty headers, BBK catted H, 3-chamber flows, and the stock airbox before I bought it. Sense then I have added long tubes, o/r h, 2-chamber dumps, and a Moroso CAI. I need to get my chip reflashed, but I'm going to take it easy and wait til I get the 24lb injectors.
The A/F is perfect at 2500 rpms (which is my cruising speed... 65mph), so I figure its ok to drive it like that as long as I dont take it above 3000. I pulled out plug numero uno, and it was white as snow.[:@]
