I'm glad to hear that you're getting the tune closer. Can't wait until I have time to put mine in. What clutch are you running?

If I were you I'd definately take out that copper shim. Jeff made a big deal to me about the fact that they totally over shim the engine. In doing so you should have a higher compression ratio and more power. I've been reading on other forums that some guys are actually running cooler with the 1 alu shim in, along with much stronger performance. Jeff also said that if your temps get over 240F, you should fatten the LSN a little.
