i have a 2007 chevy silverado, duramax diesel with the allison transmission, it is lifted 6ins, i have a intake an exhaust system and a bullydog chip, the truck moves but has a problem jumin off the line, it kind of hestitates when u floor it, like it doesnt want to and then it goes but i wanna get it to jump when i floor it, any advice?

 

twin turbos

 

Fact. It's defiantly not going to jump like agasser would. Due to the fact of turbo lag. Umm... best bet is to put mods that put low end torque on. You just won't have that jump. RPM's have to be up for the turbo to get spooling to produce power and most of the power is produced through the turbo in the newer diesels. The hesitantion you feel is the turbo lag (part between to low of rpm's until it reaches enough rpm's to have enough exhaust to spin the turbin to suck more air into the engine).

 

Also at looking at twin turbo setups besure to becareful which ones you buy. And your probably going to suck more fuel. It still won't be jumpy like a gas engine.

 

Are you really going to listen to a guy who owns a 6 speed dodge? he doesnt know what torque feels like...if you think your truck has no nuts off the line, put it in 4 high and spool that turbo up and watch that black smoke totally cover anybody within 20 feet of your exhaust...nothing goes out of the hole like a spooled dmax..u can try it in 2wd but you wont be going anywhere to fast and your probly not gonna have much rubber left. and if you still dont think its fast enough off the line, try puttin 4:10 gears in it...or just twin turbo it and shut everybody up

 

Twin turbos, propane injection, and methinol injection.
