[QUOTE="paramax55, post: 10334659, member: 114176"] We are pretty close to sea level, so 0 psi would be about the maximum that Ford should have programmed numbers for. Still, with that logic, a big cam and some ported heads should draw enough air that the thing should bog just like you said. When the Diablo chip was in there, the AFRs were all over the place. It really didn't make any sense. I don't know if someone tried to "tune" that chip or if the chip really wasn't meant for this setup in the first place. But the car did start to behave on the stock ECU. As far as the injectors go, I've been through this before. If I put the injectors in without being able to change the map, the car will simply flood and die as soon as you try to start it. I need to make sure I can alter the map where it is bogging, then take out about 1/2 of the fuel, put in the big injectors, and go for a drive. It took about 2 hours to get my BMW to run as good as factory after I swapped injectors, then it just got better from there. I'm not really loosing much time by altering the ECU first. The headaches it can save are priceless. I think the MAF is stock. I know, that will have to be changed but, again, one thing at a time. Changing that and the injectors now would be sort of like polishing your shoes before you learn to walk. slo98; I'm glad your car was doing the same thing as this one and it only needed a remap. That's the direction I will head. Now, to find a Tunerpro definition file for this thing... [/QUOTE]
