Ok, so I finally got efi, 5in check dp back exhaust and egr delete kit.. how ever I don't got alot of free time to do it all at once.. I was thinking of maybe doing dsp5 and ppei efi live one night, 1 to 2 days later getting the exhaust in and on a weekend doing the egr delete.. is there any reason why this wouldn't be a good idea? I get like 2 to 3 hrs of day light a night after work, and I'm not technically inclined enough to trust my self say I can do the dsp5/efi and exhaust in one night
