I wont be doing that haha. Have you done a http://uprev.com/secure/ Osiris or whatever? If so do you like it? What has it done?

 

Uprev is the preferred choice when tuning our cars. Its best to find an authorized dealer in your area and have the car dyno tuned for max gains. Also, get the basic bolt-ons first before getting tuned.

 

So im reading that the sprint booster won't fit and X sedan? Why is that??

 

Is the Sprint Booster fun? Yeah. For about two days, until it becomes the new normal, and you adjust to driving with it installed.

Is it worth $330? Absolutely not. For $330, as everyone else has said, I'd buy the TransGo shift kit, and call it a day.

 

Installed it is more like $800. Unless you have mechanical skills I believe the Transgo should be installed by a qualified installer. If improperly installed it is going to cause major shifting problems.

 

I always forget about labor costs because I do most of my wrenching myself.

But I'd still pay $250 for a TransGo kit over a Sprint Booster any day.

 

Would you guys buy one for $150?

 

the sprintbooster? not sure what they go for new but I wouldnt.

 

cool just wanted a second opinion ill save my moola thanks

 

I would really appreciate someone explaining how a grounding kit provides improvement in throttle response and shifts.

Something to do with electrical interference is my guess. Im still not sure if it was worth it but when you have a slushbox, every little bit helps.

 

So, Has anyone had BOTH the sprint booster AND the transgo? Which one did you have first? I alredady have a transgo shift kit, and I am considering the sprint booster to help with the lag between the gas pedal and the actual shift.

 

So this company wants you to spend $289.99 on a device that increases the voltage out of your pedal and fools the engine computer into thinking you have pressed down on the pedal harder that you have. Not only that, seems to remove the linearity of your throttle response using spikes in the voltage curve.

Am I the only one that seems to find this even the least bit dangerous?

By their own description of "how it works"...

It does NOTHING to increase Horsepower.
It does NOTHING to decrease your 0-60 times. (Wow this makes sense No HP, no better 0-60, isn't that interesting)
It DOES makes your car "FEEL" faster. (Gee so would pressing the pedal further down)
It is not for everyone (should read not for anyone).

What it DOES do is:

Cost too much money for almost no reason.
Add complication to an already complicated Electronic Throttle Control System.
Create a possibly disastrous condition if this thing were to short out while you were stopped, lets say, at a traffic light.

I can see some person buying this and having a bitch of a time trying to do a throttle relearn when this thing F's up your throttle cal.

Um lets see BAD....... Nuff said........

 

OK after providing such and indepth critique. How long have you been running one and have you tried it in either a 0-60 run or a quarter mile run? I'm going to assume you do run an AT and are not bothered by throttle lag or slow shifting.

 

Settle down, I'm not trying to start an argument. I'm giving my opinion based on observations and experience diagnosing electric anomalies/failures in servomotor based equipment. I have not tried this thing nor do I plan to!

However, if you take the time to go to their website and read the How it Works/Why it Works section, they say in some very plain English that it does not increase HP nor does it lower your zero to sixty times, so what good does it do other than making it "feel" like the car is faster? Sounds a bit like the placebo effect, aka I spent money on it so it must have done something good.

I've spent months cataloging sensor readings, asking around about issues I am experiencing with this car (namely the damn pinging) and I have mentioned this device quite a few times. Every single Automotive Engineer, or technician I have asked about this laughs it off as "snake oil". One even said you may as well roll down your window and throw 300 dollars out.

Frankly I'd say putting $300 into CAI or a throttle body spacer is a better idea but then again those ideas HAVE been proven to increase throttle response, HP and the like.

Yes I do have the dreaded RE5R05A shift lag, a device like this is flat out not going to help with slow shifting or is there something on their website that I missed? Nothing short of a shift kit or a professionally rebuilt transmission is going to help that out enough to amount to "a hill of beans".

I've heard of ground kits helping with shift lag and throttle response somewhat, obviously there is no miracle increase there but poor grounding can't be good so anything that lowers resistance would help at least a little. Anyone that has some basic electronics experience can see the benefit or good grounds (lower noise and such).
