Alright, I'm making less power than I should be considering the mods I've done to the car. This is based off my last Dyno

I had the tune pulled and looked at by another shop and according to them the car was wrong and the motor was tuned the same way an LS motor would be and the adjustments made to my transmission and shift points are the same way you'd mess with a 4L60E

Any tuners willing to take a look at the file and tell me how true it is?

I can send a list of the mods done and what specs I can find.
I just need to know if I have to spend the money on a new tune or pay someone here to do it.

Tuned with HP Tuners

Current tune is in Zip folder

[JANNETTYRACING]

[JANNETTYRACING]

HOLY CRAP

Now only if I could read these, maybe I'd know what you're hootin' and hollerin' about.
Can you elaborate for all us simple folk.

Mods are (from top to bottom)
Ported Throttle Body
MSD Atomic Air force Intake Manifold
Heads have been ported and polished
Comp Cams Camshaft with a 34% fuel lobe ( I can get the specs when I get back to the house)
Callies Forged Lower
Diamond Racing Pistons (I'll see if I can find the specs on those as well)
D-1 Pro charger with 9lbs of boost
Snow Methanol Kit
Running on 100 Octane right now
Stock injectors and HPFP. Was told it would support up to about 750rwhp, have LT4 hardware in the garage. Car wouldn't run with LT4 hardware after procharger was installed


I'm assuming by your reaction, the tune is in fact wrong

Basically car wasn't tuned the way a Direct Injection motor should be. Same mindset on tuning a LS motor.

Even the adjustments made to my trans has me wondering...

In short... A lot of time and money spent, car isn't doing what it should be

You can reach your own conclusion from the evidence.

There is no reason the car should not start and run with LT4 pump and injectors, I just did mine 2 weeks ago and the car started and ran pretty good just to drive around to the dyno bay.

The tune must be set up for this hardware.

There is no way I would try and run 750 RWHP on stock LT1 fuel hardware.

We stop at 575 RWHP.

Granted your Meth system can be used for fuel supplement but that is dancing on the landmines.

Did you increase the cubic inches?

I did, it's a 416 now. Sorry thought I stated that, hard to see on mobile sometimes.

Hell at this point I'd be happy with 575 RWHP, send it across Barrett Jackson and move on to a ZL1

But the way it feels now, is just WRONG on so many levels..

Problem will be finding someone in town that can do the tune, I've heard of one person, but problem is a lot of the shops around here talk shit about each other.

Just going off what Jannetty posted, the MAF scaling is so far off a stock LT1 it's irrational. Not to mention the shaping smoothness is pathetic. The timing table is also janky.

Please go to a real tuner like Jannetty and get your tune sorted out. It kind of amazing your car runs at all. If I were you I'd garage it until at least a safe base tune can be sorted out.

Edit - just DL'd your tune. LOL your cam phaser is turned off. DOH. Looks like they also messed with your idle, and ironically the cam angle mapping. Also, they really messed with your pedal mapping. Is the pedal really sensitive feeling? Yea there's a whole bunch of strange things going on here. Kind of confused how whack it is.

Yea, peddle is sensitive as hell, 10% throttle almost feels like 50%
