Just for reference:
You can see all my mods in my signature, but hear are the main.... LT Headers, 87 TB, .5 CAM, CAI, B2 Exhaust and Tune by Jay Greene.
rwhp was 374 / rwtq 418 with just a basic tune after that Jay Greene started with a few adjustments and data logging it more and more... Now we believe it is about 385 or more.... I will go have another dyno done next year. For sure there is still a little more hp left in it. Jay is supper at tuning, I know I will be or I am already am at 400 rwhp.
the first pull was 341 rwhp with mods of: LT Headers, 87 TB, CAI and the B2 Exhaust
Hope this info is helpful. see dyno chart attached.... Keeping in mind this is before Jay started doing multiple tunes and me sending him data log... data log
Great Dyno sheet. No offense, but your not making 420rwtq. That's a spike at the start of the run which is common. Your making 365rwtq which is still a very nice and substantial gain, just thought I would point out the true tq number which is very very good still.
