I saw this on the QTP website...the B&M Shift Plus

Shift Plus simply recalibrates your transmission's hydraulic system electronically. The Shift Plus shift firmness not only makes driving more fun and pleasurable, but slippage and heat are reduced - extending the life of your trans- mission! Anyone can install a B&M Shift Plus in minutes with a few simple hand tools. This new design allows you to improve the transmission's shifting performance with- out removing the transmission pan or valve body. The B&M Shift Plus electronically enhances shift quality and is adjustable. A simple flip of the switch allows the transmission to operate in the performance mode. Flip it back and you ore back to stock!

Is this a worthwhile mod to do....or should I just save the money up to buy a Preadator to do the same thing?

Thanks

 

No. It sets the line pressure to 100% at all times, slamming into every gear at low speeds. It has no effect when at WOT, so whats the point?

If your going to blow 500 bucks, dont do it on a lackluster handheld programmer. Get LS1Edit.
