Uprev vs Ecutek

redondoaveb

My mechanics g37 with bolt on's and e85. Granted it's on a dynapack, but still great numbers.

If it's not a dynojet just throw the numbers out the window and focus on the before and after number gains. I find these numbers hard to believe with just a tune difference and a few months. Those numbers do however look like a gearing change. There's just no way 19.69 peak HP between tuning software unless the uprev was a sh*t tune which I doubt if it was the same tuner.

All are uprev from a customer of mine.

The blue is tuned 4th.
Red is tuned but with my ported upper, lower and TB's added in 4th.
Green is same as red but 5th.

I agree. These numbers are much higher than others with similar mods. I was hoping for somewhere in the 320's, so this blew me away. I plan to call PTuning and ask for the initial dyno results so that I can compare the numbers before the Ecutek tune. I'd also like to know what gear he used. Although I would like to put it on a Dynojet, I just don't have the funds for that right now. This tune and a brake job were the last two things in my budget for the next six to eight months. Yesterday while doing my brakes I noticed an insane amount of ozone cracking between the treads on one of my rear tires. I'm sure this is the result of being a garage queen with very low miles on eight year old factory tires. So now I have to drop several hundred bucks on tires so I can safely run the car on Road Atlanta at the Z Nationals next months, so there's just no cash right now for another dyno run.

I completely agree. I ran a dyno jet this summer, went from completely stock to what I am at now. stock run on a dyno jet I was 268 WHP. after 4 months of working on the Z and 10K of parts installed with an UpRev tune I'm only 317 at the wheels without nitrous. 344 is impossible N/A I can't see those numbers being legit

268hp seems really low for stock. I thought the average was somewhere in the low 280's?

Although I'm not arguing that my numbers are off, I don't think 344 is impossible on a NA motor. The exhaust cams combined with other bolt-ons may very well produce those numbers, but their installation requires a great deal of work.

Hey man, not knocking on you at all. I believe he saw those numbers, I just don't believe that dyno is calibrated right.

268 is a pretty normal stock pull on our cars. I'm up in Canada and at the time of a base run I believe the humidity was 46% our cars are usually between 265 - 285 stock on a dyno jet. so a run of 268 especially at the humidity and elevation I'm at seems right on the money.

My Z is running all the engine mods I believe you can get besides going forced induction. its also been tuned by UpRev themselves also custom building me a MAP right form there own office. Im running the Motordyne 400 HP package as well with a full header, exhaust, & intake manifold replacement and I still can't break 317 hp.

If he has some upgrades on his car that are actually pushing it to 344 on a properly calibrated dyno, then I will rip my engine apart and put his same mods on because those numbers are impressive if there legit!

Have you considered the exhaust cams? I've read a little bit about them. Their claim is an additional 30whp gain.

I actually did consider a cam but the gains were not worth the cost to me. The biggest gain I saw was a 30+ torque and a max of 10 hp increase and that was with no dyno charts to back it up.

The cost after labour was almost $2500 - $3000 CAD... i also looked into a lot of the reviews and I was coming across a lot of people putting the stock back in after a while because of constant issues.

I had mentioned the cam to UpRev before the tune but had been told by UpRev themselves that they have seen serious issues with tuning when changing the cam out, so I would likely loose the UpRev power gains due to the thresholds changing to accommodate the new cam.

Here is the response I got from the email I sent to the tuner:

"Rob, I did not do a baseline on your factory tune, since most cars come in with the AFR’s far off from where they need to be. Your dyno pulls for the tuning process were all performed in 5th*gear. Dyno Dynamics does normally read lower for most, but not every car, in comparison with a dynojet."
