I just purchased an extra ECM for my 05 (LLY) I'm looking for suggestions on where I can get a couple of tunes. The ECM was part of a package deal with EFI V1 so the ECM is registered to the V1? At this point I'm interested in a tow tune with turbo braking plus a mileage tune. I have an FE9 truck in Calif, but still would like the EGR blocked as well. I'm not planning on racing the truck, but I do admit I enjoy the extra power gained from just the few add-ons mods so far....Any help would be appreciated. I can ship the ECM out next week if needed, but since this is an extra ECM I'm not in any rush. Any other suggestions for additional mods would be great. I am planning on a lift pump next year, and also looking at Suncoast Hoods or the Banks CAI with the air scoop...If my job hold out I'm also looking at the Banks Larger Intercooler as well. I use the truck mostly for towing....usually in 100 + temps through the Calif/Arizona deserts....so far no issues regarding over-heating...
