Losing power

I lifted my 2010 creemax with 7 inch suspension, 20x12 wheels, 305/55 20 tires, added a corsa cat back exhaust. When I accelerate from first to second aggressively, the power dies and traction control light flashes. Plus, the low air pressure light stays on and flashes occasionally. Help!

 

Would that cause the loss of power?

 

OK....I may be a little confused. When i lose power, I'm not spinning or leaning. It could be on a straight away simply gassing on it. As it hits second, the power dies and it takes roughly 4 to 5 seconds to return. The same with third. Are you saying a speedometer calibration should fix the issue?

 

You need to do a zero point calibration. Zpc. This is most likely the fix you need. The dealer can do it for you, usually 100 bucks, or you can research it and do it on your own. This thread has the answer for you, but Dont take what you have to do lightly or you could meas your truck up. My scary little warning to you... I can tell you, I did mine successfully though.

Yeah the calibrator made my truck feel a lot better after 35s. Mine was shifting really weird before the hypertech too. Was your TC light blinking though? I think that's the dead give away with this guys truck though. Plus that 3-4 second delay in shifting from 1st to 2nd.

The other thing you may want to check, OP, is the wires to you wheel sensors. Make sure they aren't stretched or loose.
