Mine only out puts like 3.8 to 4. But according to what I just read should be 4.5. It runs fine but the tps does seem to have a dead spot right after closed throttle that's very small you wouldn't ever know unless you held it in park and pressed it just right. But should I get one or no? Getting around to getting some extra parts and though I have no real problem with my tps I may just replace it anyways. Maybe that's why my truck kinda falls on its face at 5k rpm.
