Low numbers after tune

dragoo · 01-15-2019, 08:56 AM

Got my car tuned yesterday by local tuner. Car has TSP headers, dry Rotofab and e85(reading 48%at time of dyno run) just trying to see if this is normal. I know numbers don’t matter but I looked at the dyno and it dips around 5.5 to 6.5 rpm.

Thanks for any input

1) What was stock?
2) What do other LT1's do on that exact dyno?

lol i think your numbers are okay, but before you go crazy about it, try a different dyno, some read less then others even with it being a dynojet.

Didn’t base line it and another 1LE without e85 got around the same maybe -12hp

I can almost guarantee the car is pulling timing up top which is the reason for the dip. This is pretty common with headers and even some stock cars, and is also a super easy fix. Do you happen to have a data log?
What tuning solution are you on?

Almost exactly what I make with same mods. A8

Its the tune, most likely hit a torque limit and pulled timing. Who tuned your car?

You're in North Carolina? Hit up Pray.

The numbers are fine, basically the same numbers my cars makes with same mods. On a different dyno it might be + or - 30 hp either way. As for the dip that could be something to look into but don't worry about your numbers.

#1 without a baseline you can’t verify what you picked up

Dyno’s, depending on set up, will give very different #’s
Hope you used a reputable tuner and not the Craigslist guy who was $200 cheaper than a true shop.
