Default SLP Kits, Does anyone have them??

If so, what kit, how much of a difference did it make, and would you recommend it?

Thanks!

Do you mean their ZL435 or ZL465 kits? I piece mealed their 465 kit. The only SLP part I used was their 1.85 rockers. So with Kooks 1 3/4" long-tubes, Halltech cai, rockers, x-pipe with cats, Corsa Cat-back and tune, my car made 393rwhp/383rwtq SAE. That's basically the same parts in that kit and I assume using their parts would get you close to those numbers as well. I think they now include an u/d pulley as well.......maybe gears too for better acceleration. I later add a ported intake which brought me up to 397/387 at the wheels. I didn't want to open up the motor at the time but now looking back, I think I should have just gone with a cam. You will get more power even with a mild cam over the rockers.

I have the ZL435. I am very happy with it. I can definitely feel the difference SOP. I have recommended it and the people that have done it are very satisfied with the results.

We have not yet. We are working on getting the ZL500 (like the ZL465 Kit you saw) into Car and Driver for the more "official time" comparison.
