The 1st time out we tested 2 2012 srt8 with diff tunes. Mine is bone stock and the other one has a cai and 93 canned tune with a tad more timing added thru datalogging. Im not sure where he added the timing but were using ca 91 gas in testing. Now the only diff in the race wt was mine is 105 lbs heavier. So if you take away the wt diff the cai and 93 tune was werth .10 & +.67mph. Now the other car is getting his e mail tune all dialed in so when that happens we will be testing again and ill be running the same stock set up. We will keep you informed on all our test But our DA in CA wont be -DA IT WILL PROBABLY BE IN THE +1000+ DA. Now the wt diff is our body wt which is 55 lbs and i have the trailer tow package which is 50 lbs and thats a total of 105 lbs. Now our options are the same except i have rear dvd and reg moon roof and he has NO rear dvd with panasonic moon roof so ill call that a wash.

This next time out i have 2 gal of unleaded vp109 race gas that is 10 months old and ill be getting some fresh 100 octane to mix with our low oxygenated 91 to try and lean the tune down even more this time and along with taking out the air cleaner just to see what the stock tune will put out. I ran the DA THURSDAY NIGHT from 5pm to 8pm to see what we will be in for as the temps are getting higher and the DA at 5pm was 2250 ft (80 DEGREES) and this is when we make our 1st pass and at 8pm it only dropped to 1650 ft. The water grains in the air were at 55 so that was staying steady but 50 and below is best. The other jeep with the tune will be datalogging and im not sure what gas he will be using as i no he wants his e mail tune with 91 gas to be all dialed in b4 using something else. We will also have another 2012 stock jeep out there this time so we will see what he does and he is about 60 lighter than me so we should be a good race.

I'm curious to see how close the tuning will be for the '14 from the '13 Maybe it will be a little quicker for them to solve, since there seems to be a big difference between the 12' and 13'.

it couldnt be too much. Only differences I know are the TB and the split in track mode. 13's are 30/70 where the 12's are 40/60
