Well got my dyno numbers back
250rwhp/300rwtq. Not wat i was expecting, but i have issues
Now i have just recently had trouble with the truck, took it to the dyno today and it put out 250hp/300tq to the wheels but the air/fuel ratio is not where its supposed to be, it idled at 16.1 and at 4k+ it really leaned out, if i can get a pic up i will of the chart, but I am not sure if the fuel pump is not effecient enough for the lt1 (i have my stock 2.8v6 pump in the tank still) or if injector(s) are bad. If anyone has input please let me know.
let me try to get the graph up here so you can see it visually.
