I have a 1993 GMC K3500 4x4 dually with a TBI 454 and the 4L80e transmission.

I'm looking to give her a little more towing pep by going with a carb on top of a weiand 177 blower.

I also have a pair of 781 cylinder heads in my garage.

I noticed that stand alone controllers for the 4L80e have come down in price.

Have any of you ventured into a conversion like this?

What have you done to increase the power in you 1988-93 GMC/Chevy trucks that was/is TBI?

Thanks in advance!
