my boost controller is set at 19 but i am only getting 14 pounds of boost????

[98FWDSM]

ok, i have a automatic tranny and i just did a fuel pump rewiring on the stock fuel pump and was planning on running the T28 that i have at 17 pounds....well i dont know if it is because i have a auto tranny or what but if i have the car floored then it will only be boosting at 14, and in between the shifts it will go up a couple pounds....but the strange part is that if i push the gas pedal very slowly so the transmission doesnt downshift and the boost is going up slowly than it will eventually go all the way up to 19 and stay there until i let off, but if i have the car floored then it will only go to 14....figure that one out??????????

Thanks
Chris

how do you know your setting is at 17lbs of boost do you have a AVC-R or an ecltronic boost controller? If so sometimes they can be off a 1lbs or 2, my suggestion is to check to make sure you dont have any vacume leaks that could cause the boost gauge to read low, something does not seem right???? are you sure everything is install right ie boost gauge, boost controller? check and make sure!
