New #s!

OK I was hoping for 315 but I'll settle fo 316 HP, 330 TQ. I'll post the graph later. Mods are in my webpage, which is in sig (page 2 I believe...) Anyways what do yo guys think?

I gained 11 with PCmforless, an airfoil and the LT4 KM....my Lloyd Elliott heads should be going in about a month so I'm looking foward to that.

Do these #s seem right for my mods?

Here is the link to the dyno graph. For all you lazy people, here are my mods.

Engine: LT1 with LT4 hot cam kit (1.6 RRs, etc)
-Exhaust: AS&M headers, high flow cat, cutout (open) Flowmasters catback.
-Induction: SLP CAI, TB airfoil
-Computer: PCMforless, LT4 KM


I think that's all my speed mods.

I dyno'ed in 4th....after my head swap I'm doing it again and I'll do one in 4th, one in 3rd....see what the difference is.

Thanks for the compliments TunedPort!

You should do it in third most of the time for tunning purposes and your last on 4th to see the total...

3rd is a shorter gear and it will give you time to abort before any damage is done if you go lean or something since it is a lot less prone to detonation...

Afterwards you can finish it on 4th for timing.

Interesting. I've never heard of tuning in 3rd and checking in 4th. I would figure since 4th is going to take longer to rev, you would have more time to let out, while 3rd could rev too quickly. I have heard that turbo cars should dyno in 3rd, because 4th "pulls" the turbo, and can give false numbers.
