Default wont idle, raw fuel out the exhaust, breaks up above 2 grand, 450s+crome

well title basicly says it all...i have an ls-t that i cant get running. i have crome with p30 program with -28 maps and boost tables with 450s and OBD-1 swap. i couldnt find a schematic on here for my dizzy so i printed the ones off of alldata and came up with one that got me spark and fuel. do the cylinder ID wires need to be ran to the computer? i tried going into crome and changing my map and i cant take any more fuel out. my wideband wont even register it just says "rich" haha. one thing i did notice is when i try to go change from 240s to 450s and from 1500 cc to 1800 cc it doesnt save it? when i click ok and go back to it, it still says 240cc injectors 45 psi and 15xx cc displacement, is this normal? thats really all i can think of right now...if i think of anything else ill add it later. this has me stumped...thanks in advance for any help

ive read the guide and all this but i got pissed and sat down and looked at my maps tonight and i figured it out. i stared at them for about 45 min and messed around with them and burnt a GOOD basemap now i got a decent running car no more puddles of fuel!

i went into the multiplier calculator typed in 450 in the new injector flow rating and changed the new engine 1834cc. it ran better than befor but its still REALLY rich. i went to xenocrons .bin dump and found a map thats pretty much my set up. its the Jon-Ls-DA-4.bin and the car still runs really rich. theres gotta be something else im missing... ive went over every plug on the car compaired a BUNCH of maps and i still get the same results. i dont really like asking for help on stuff but my nerves are at their limits now

Reburn your chip for 450's. I had a map that was suppost to be for 450's.. It wasnt and the problem was exactly like yours. Retune on uberdata or crome.. Try uberdata because chrome does that stupid ---- your taking about until you figure it out.

i change the injector sizing and it shows like .533 in the adjustment...i hit OK and it changes the map. ive tried to take 5% out...PLX says "rich" and jumps to about 11.3 when i let off the gas... just like it should...ive took 5% out for like 3 times then i jumped to 25% with the same results untill the maps read 0 for the first few cells...im stumped... :1
