First post here, so be gentle. I have a 00 GTP coupe and I have the typical lower intake manifold leak. My question is two part: do I need to tune if I replace the LIM with the ported one offered by The WBody Store, add a plog and the ceramic coated crossover pipe and a CAI or can I run the stock PCM to support those mods? Also, I know the ported LIM is set up to run an IC, but is it okay to run it without an IC? I thought I'd do these few mods now since I have to fix the leak and get the car to run a little better. Any input and/or suggestions is much appreciated. (And yes, I know how to work the search button here but I haven't found anything regarding this specifically. I've been researching on here for quite some time as I plan on MAJOR mods in the spring and the wealth of knowledge and help from everyone here is awesome! This is the best forum out there )
