Westers GXP tune Results

Sure is that all you want to see?

RPM
Which MAF? Frequency?

AFR or EQ? and Commanded vs Actual?

That would only be 4 so Boost/Vac and one other?

BTF might need this tune to release some of the nanny issues hes having.
Thats what people on the Saab forum are doing with thier 2.8 Turbo and a smilar motronic ECU.

Buy a canned tune to get rid of the nanny controls and then tune by hand for aftermarket stuff.

I understand from a different forum that the RSA keys are a real pain

Here are my drag times with the westers tune on a bone stock car. I am number 545. The 14.2 run was because I hit traction control and it screwed me up.

How does this compair to a stock GXP?

today i got a 13.51 at the 1/4 mile. I'm not stock but then again, I was really babying the car, and shifting normally.......and on the crappy stock tires.

I really think that with slicks and a more aggressive (better) driver, very low 13's are within reach with my setup with wester's tune.

I have video of my runs both in car and from the stands, as well as pictures of the slips which I'll post when I'm not exhausted, ha. Hopefully get those up sometime this weekend.....

New Dyno to come hopefully this week.

Well numbers usually do not lie, and in both cases the actual BHP of the car is about 252 - 255 BHP and not RWHP.
I agree if the car had some drag radials or sleeks and a good driver it should be a little lower.
I see a lot of Dynos etc with big RWHP numbers, that translate in the 300 + BHP.
Well folks if you have that much BHP on a car that only weights 3080 with a driver, you should be posting 12's numbers.
Let me give you an example 320 BHP on a car weight of 3080, your 1/4 mile number should be about 12.3 - 12.4 and around 110 MPH.
The above numbers are with sleeks or drag radials, with some good sticky tires probably in the 12.8's.
You can all post BIG Dyno numbers but the proof of such numbers are in the Drag strip, otherwise is just make me feel good numbers.

Feel good numbers, very likely. However, the cars could be putting those numbers down, but area under the curve just isn't sufficient to give you a decent time.
Figure a 3200LB camaro can put a 13.0-13.5 with 280RWHP (stock). So, drop the weight, yeah, high 12's. However, this isn't an LS1, and it's not making 300Ft-lbs right off of idle. Think about dyno queen supras- they post true 600RWHP+, but often 12 second time slips. When my procharged camaro was terrorizing the drag strip with 550RWHP, it was running low 11's on street tires, traction limited. Better times, with less power- because it was about area under the curve when it comes to drag racing, not peak power.

[LatinVenom]

I am not really talking about peak power, but you see 260's 280's RWHP been advertise all the time, with those numbers people should be posting 12's all day long with a car that without a driver weights at 2890 lbs.
I am OLD drag racer, have not done it for 30 + years, but had a dragster and a few other drag cars.
Dyno's are strictly for tuning and not for bragging rights, and that is what happens time and time again on this and other boards.
Our car GXP bone stock with a good set of sticky tires will post 13.4's all day long.
Although this car was made for the race track and not for 1/4 mile strip and that is the way I like to use it, lots of curves .

[Moose GXP]

I could really care less about what a stock GXP or a tuned GXP does at the drag strip. So much of your 1/4 mile time is up to the driver's ability. Going fast in a straight line is something special for LSX vehicles, not LNFs. I know guys with LS1 GTOs that can't get their times under 14.2 and that car is capable of better than that.

I had a dyno completed on "Renee" I have the Solo CAT, Magnaflow Exhaust and Dejon Surge Valve spring. I am 1 thread reverse of the wastegate mod to prevent knocking in 3rd gear. Boost is not displayed on the sheet, but the log stated 21.5.

[chuckdoc]

Deep, those are great numbers. We had a perfect day yesterday at the dyno. But I have two questions.

Does anyone out there in "dyno expert world" know why the automatics with exactly the same tune and mods on the exact same day and same machine with the same operator got results that were 40+ HP less? Is it just a function of the dynoing of automatics or is something else going on? Don't get me wrong my car is also "stupid fast" and I am very very happy. I also think that the 1/4 mile times will be close as soon as we can take them to the track. Just looking for an explanation.

Secondly, Deep, you said you were going to bed yesterday and would not post on the forum until today. Checking your posting times, you and I might, just might, have not only a solstice addiction but a forum addiction. Can not wait until our next mods. I know what they are! One for the cost of paint and the other, well there goes another 1000 bucks. Keep up the fun.
