Hey SprintBooster, when ordering, what code do I give to get the free shipping?

Guys, I usually peruse the LS460 forum. My car definitely has throttle lag.
With their offer of a 30 day money back, how can you go wrong?

 

All Lexus orders are tagged to go out with free shipping on our website www.sprintboosterusa.com, and you will likely see your item arrive within 1 or 2 days. and from there you have 30 days to try our product. If your not besides yourself on how well your throttle response is, send it back and receive a full refund.

 

Do you or will you have an application for the 98-00 LS400?

 

IF that Lexus platform (year range) has an electronic throttle control then its possible. But it is not on our R&D schedule for this year.

 

anyone got this for a 2007 gs350

 

Actually, I don't find this thread depressing at all, but everything comes down to perspective. I completely feel for Kurtz in that it can make the driver "feel" different responses, mainly if you drive very conservatively. I'm a very "spirited" driver, I just started to drag, and I intend to track my IS 350. This product would not be very helpful to me becuase I'm WOT half the time anyways. On the other hand, conservative drivers that have "spirited driving moments," who, let us say, are afraid to go WOT, would greatly benefit from this because in their mind, they are not going WOT at 80% (pedal to the metal feeling from drag per say), but the car is going WOT because of the spirit booaster. Personally, I would think (no statistical analysis) that there would be more conservative drivers than aggressive, this is a sports car so there is some intended speed from buyers so there should be a strong market for this.

Applying it to my wife and I would be a good example I think. As I said in the above, it wouldn't do me much since I'm at 80%-100% throttle anyways. Using some just very generalized figures to show some variances:
I'm driving, I've got the pedal 80% down, the SB may tell the ECU I'm at 88% (8/20 with 8 being the increase % and 20 being the difference until 100%, would be 40% increase) therefore I'm getting a tiny bit more responses. At 100% though, the SB should do nothing.
My wife is driving, very conservative, pretty much goes the speed limit at best, goes 40% throttle. Holy crap, she's late for work and pushes the SB button and it kicks it into gear. Well, knowing my wife, she's going to continue to stay at 40% throttle because she's just that conservative, but the SB tells the ECU she is actually at 64% pedal (24/60 with 24 being the increase % and 60 being the difference until 100% this keeping the 40% SB increase). To her, she'll crap her panties and say, "damn, my car feels like it's at 64% while I've only got 40% of the pedal down!" I'm sure it'll eat gas like 64% though.

Again though, I'll probably state what Kurtz is trying to phrase, "why pay $329 when all you should be doing is just pressing down the pedal more?" Well, one reason is lack of courage, another could be fear of breaking the car, fear of going overboard, etc... Of course, I'm saving my $329 and try to get a pair of used 18" rims, and a pair of matching drag radials.

 

Yeah, I think 98 was the first year of the drive by wire system for Lexus. I don't know if this makes a difference but we have floor mounted gas pedals. You should definitely look into producing this for the 98-00 ls400, gs400, and sc400.

 

I have a LS460 and installed my SB last weekend. My driving habits range from conservative to mid-throttle, depending on the situation. It makes sense what you say and is evident by the added pleasure I get from this mod.

Not only did I get an immediate gain in driving performance, but as the ECU "tunes itself" to my new habit, it's performing even better.

I posted a review in the 460 forum with install pics coming this weekend.

Bottom line, it's the best mod for the money for this car and personal driving habit.

 

The guys here at JRP in Toronto installed it on my car and let me try it out for a while. I found that the thing the SprintBooster did best was to give me a much more linear feel with the throttle in low-throttle applications... like starting from a stop, or just having to creep ahead a bit. Coming from a car with a cable throttle, the electronic throttle was lacking something in response... especially with the manual transmission.

In no way did my car feel faster, just nicer to drive... spirited or otherwise!

 

My (mostly) positive review is here: https://www.clublexus.com/forums/per...006-is350.html

 

Some people cant wrap their head around what feel better means. But you said it just right. Thank you for reviewing our product and we still encourage everyone out there to try it and experience it for yourself. You wont be disappointed.

We have recently restocked our Lexus supply, please feel free to browse our website at www.sprintboosterusa.com

 

What I think would be interesting is a steering booster module. This device would provide variable steering ratios and variable steering assist depending on driver preference. If BMW is guilty of vague throttle response, Lexus is guilty of vague steering.

Not to take anything away from improving feel in throttle as when driving near the limit, steady application of power is crucial, but I think that I could argue that steering is even more important.
