A canned tune is something that you would get when ordering a standard SCT programmer. It will come with a general calibration. Lund will have you data log and send the logs in for tweeks to do tial in the tune. On the dyno or on the street with a tuner you use logs to dial in the tune. So it is...

So are you racing at sea level or 3900'? Big difference there to. I live at high elevation and tried to tell you what you need to do if you want the same power. If you want the same power at 10#s sea level, then pulley it to make 12-14#s at higher elevation. Local guy just made 600whp actual on...

Pulley down for 2-4#s more then what you want. So if you want 10#s at sea level, set it up for 12-14#s at 6700'. That will get you close to the same performance. No magic formula though.

Oh, that makes sense. Yeah a few more degrees will be picked up on e85.

So, the timing advance from the 91 tune to the flex e77 showed no additional timing? That is so strange. The major gains from e85 should be from the increased timing you would be able to run. Did you log the a/f's for each run? Maybe the e85 tune was more dialed in and that is where you picked...

I live at 5200' elevation and we typically have 7000+ air density. The thin air robs us like crazy. A 5.0 with 10#s of centri blowing at sea level will make more power then 10#s at 5000+'. Now a 5.0 pullied for 10#s at sea level will typically lose 2-4#s of boost on the same pulley setup at...

Any blower with almost instant boost is going to be a serious tire fryer. With 3.73s, it is going to grenade those tires. The centrifugals are building boost with rpm, a little easier to manage. Do you want the tire frying, sideways torque or something easier to manage is what I like to compare...

Educate yourself a bit on data logging and what e85 is. Not sure how accurate the stock gauge is, but 8.8 a/f is more then super rich. It could actually cause damage to your motor. Put the 93 octane tune back in until you can get it sorted out. That is where the missing power is at.

I am running Nitto NT05r 315/35/20 drag radials with Eibach springs. It looks real close, but for the most part, it does not rub. I cannot remember my offset though. Running them on Niche wheels.

Hood shake is normal for the stock car. Worse when you have a blower with a open air filter that lets the backwash out under decel.

Check for belt slip, although with a 3.6" it should not be there unless the belt is to big and the tensioner cannot take up the slack. I don't recall seeing spikes with a centrifugal setup. I see plenty of my twin setup.

You gained 3mph in the quarter with the GT350 IM?

Speed is addicting, lol! I have a 2012 Kawasaki zx14r.

110 would be doable, but you will need full bolt ons, tune and need to run it when it is cool, late October. N/A cars usually lose a full second and 8-10mph up here from sea level and that is when the air is the coolest time when the track is open.

Unfortunately 115-116 will not happen here unless you add boost. The thin air kills up here and you would be lucky to trap 104-106 stock.

What did you actually make uncorrected? The high elevation is a huge factor in correction that makes that dyno ready quite high. But is is fun to see the numbers it spits out.

Looks like were over at the Dyno Edge. Great shop! I wonder why the correction factor was so high this time of the year.

At our elevation, a blower car will be faster then a naturally aspirated car making the same SAE numbers on the dyno. Typically up here the correction factor is anywhere from 20 to 24% correction. Of which a blower car is really only down about 15-19% and a turbo car that has the boost turned up...

I am at 5000+' elevation, I had a Ecoboost Explorer and it did not make the same power at elevation as it did when I drove down to sea level. I even had a Livernois tune on mine. If you have a custom tune that will increase the boost at high elevation, then you can get similar results to a stock...

I think 5mph gains from that combo is pretty good. Get that sixty foot down in the 1.6 range and it is a solid 11 second car.
