Re: LS1 throttle enhancer If you are talking about the article where it tricks the sensor into going int WOT earlier I do not think that is worth doing. Just press down the gas more if you want more power. The enhancement showed power gains over part throttle acceleration because it thought the car was under more load that it was, giving it more timing.

Re: LS1 throttle enhancer Exactly, then whats the purpose of the tb bump stop mod. I would think it would be the same only better, b/c you dont have to mess around.
Oh the kit is at lmperformance------------>
I want to get it, but I need the article so I can make the thing.

Re: LS1 throttle enhancer guys from what im hearing this has nothing to do with the bump stop mod. all this does is makes your throttle body go to the 80 or so degrees that it normally would.. just faster. it wont open your tb up to 90 degrees so it wouldnt give you any better 1/4 times or anything it just tricks the car into thinking your pushing the pedal farther than you really are.

Re: LS1 throttle enhancer 
Re: LS1 throttle enhancer No, it doesn't make the throttle open faster or anything like that. There are two timing tables for these motors. One is for part throttle and then when the TPS moves past 70% or 80% a more aggresive timing table is implemented. This kit fools the PCM into using the most aggresive timing table at what ever TPS setting you choose. You could therefore have the most aggresive timing table at say 20% throttle opening. IT will not make any more power or lower your ET at the strip. It will just make the car lunge more when you tip into the throttle from a roll.
