Moby, it was rich before the I/C install I am running the dsm's wth your maps and it was rich but ran good and without the I/C, rough idle but power from top to bottom, and I did have it running like 28 psi base fuel pressure with my aeromotove rrfpr and msd pump, after adding the I/C I upped the fuel pressure to the 40 psi it should be at, and leaned out the bottom (idle range) and cold start maps, it's got the best idle and cold start it's ever had including the stock system! and of course triple check all the couplers and no problems there although I did blow one off when racing on sunday, I am strongly considering a vertical flow intercooler to shorten the piping and I really need to tune the maps better, we're about 600 ft above sea level here an I suspect my feul system flows a bit better than your did so i need to thin the maps to compensate for my extra fuel flow, and btw I really appreciate your sharing of info and maps without it I'd have been screwed
