I have a friend who has a 2004 chevy silverado 4.8 auto ecsb. Mods are magnaflow exhaust, Richmond 4.10 gears, Dynatech supermaxx headers, and a yank 2600 tt. For some reason the yank will flash to
2600 but when brake stalled it only will stall up to 2000. I would think it would stall up more than that because I bought a yank 3000 tt and it will stall up to 3600 easily. Can anyone help with why it does this? All help is appreciated thanks
