too damn cold out there !, what ive found so far I correct myself I have a 75mm tb and spacer and a c&l 76mm maf and tube in between, c&l color codes there calibration tubes and I think you guys have pointed me in the right direction,after looking at all the charts there is no color coded tube listing for 36lb injectors for 76mm maf , mine is color coded red which comes up for 38lb injectors , so at this point im thinkn I need to drop to 30lbs and keep the red tube or step up to 80mm maf and keep the red tube as far as the charts say either way would be correct , what do yall say ?
