Radix Questions

[STEPSIDEZ71]

I have been tossing around the idea of getting a magnacharger Radix System for my 2006 Crew Cab Z71.

 

But my wife is on me about the gas mileage. I currently get 15mpg. Would a Radix effect the mileage just driving normal. I know for a while I will be on it all the time making the gas mileage go down, but as far as just cruising down the highway is there any negative effect.

 

Second Question is the transmission. I have done a lot of reading and it seems like the trans is weak. Alot of the guys who blow up transmissions have alot more done than just the standard Radix. Will the transmission hold up to just the radix kit with no other mods. For a while I would just run the kit stock. Is the trans strong enough for the stock radix kit and tune?

 

Thank you for the help.

Mileage with the Radix wont be all that much worse unless you stay in boost all the time.. Its just like any other mod.. If you take it easy then you can get good mpg but what is the fun in that.. As far as the tranny the things barely hold up in stock form.. adding 100+ hp isnt gonna help.. Id suggest atleast a shift kit and servo update..

Mileage might go down at first. That's because your going to lay into the throttle more after the kit is installed. It will usually remain the same or possibly increase when you go back to normal driving.

 

Another vote for a shift kit. The stock tranny can be fine during normal driving but it will be benefical to at least go with a shift kit. That will add some strength and help the tranny live longer during hard use. I have some customers that have been using this kit with the stock tranny for over 20k miles. No problems. But they also doing drive it very hard.
