Going on the dyno tomorrow for E85 and injectors
 

Taking my 2013 auto ZL1 to fasterproms tomorrow for E85, injectors, 2.5" pulley, and a tune.

Car has long tubes, 3 inch exhaust over the rear up to stock mufflers, stock injectors, 2.75" pulley and a crappy tune.

What do you think it'll make?

In the neighborhood of 100 engine more hp.

622 HP / 635 TQ

Stock cam?

What did you do for fuel supply?

What does it feel like to you do drive it now compared to stock.

What did you wind up making?

yes, as far as I know. Nothing appears to have been apart before

Brand new stock ZL1 pump, the FPCM was reprogrammed as well. I believe I've run out of pump so I'll have to add an auxiliary pump to get more out of it

622 HP / 635 TQ on E60

599 HP / 613 TQ on 93

1000% better. The throttle response and shift points are spot on. Jeremy Formato really took his time to make sure it was right. I wound up picking up MPG on the highway. I used about 9 gallons to do 110 miles to get there and only 7 to get home

All in all he did 7 pulls on the dyno with a cool down in between. The we drove it on the street while he made adjustments until he was satisfied

dyno sheet

What the hell is going on on the power band? I have never seen a dyno sheet look like yours. Every dyno sheet I have seen the power band lines are straight and not look like the power is up and down? Please educate me on why yours looks like it does please.

Looks like possibly the smoothing setting is different than 5 or the car is not strapped good on the drum.

@53 L W already answered that part. Having the graph artificially smoothed too much might hide something so it's better not to do that unless the customer wants a pretty one.
By the way dyno operators can also plug in numbers like temperature and pressure and altitude to make the numbers on the graph move up or down and not represent reality. Happy cusomers that aren't real racers looking to determine what real times they will run prefer a mine is bigger than yours.
This isn't a dig at the OP awsome car, it's about dyno games.

I just noticed the 93 and e60 numbers. Not talking about what peak numbers STD vs SAE etc, the spread there doesn't look right. I don't really care to say more and have no bad comments to make about your tuner. Just pointing that out and others might care to guess what's going on.

The only thing I can offer is that 622 number was on the 7th or 8th pull so the car was hot. I believe we also ran out of fuel pump so to speak. My tuner did expect it to make more but was thinking the heat was an issue.

It has a brand new stock ZL1 pump so my next step is to add an auxiliary fuel pump to solve the fuel supply issue. https://dsxtuning.com/collections/au...nt=58596002379

Also going to add spacer plates for the blower to lower the temps as well. I might research adding a higher flowing intercooler pump from prospeed https://www.prospeedautosports.com/c...pro-09-07-1005

Let me know what you think?
