Precision EFI Tune

[MrSled]

Mr Sled who did your flash? I think Pats motor sports is now a Precision dealer and so is Ullmer. Pretty sure this is the direction I'm headed

Have to disagree with you, Precision Efi is taking over. They just don’t come on here and talk about how great they are. Would not hesitate to run their tunes

Um, I run PEFI Stage 4.

Yes I get that! But to say their focus isn’t in the powersports aspect of their business is false. I have a friend that recently sited their facility and it was full of sleds not cars.

I run a Hurricane stock muffler tune on my sled and it runs flawless I couldn't be happier. My friend has the identical sled to me with a Precision stage 3 and a Sandale 3" Heartbreaker exhaust and it also runs flawless and is dominant in head to head competition with most Winders and he couldn't be happier. Pick your poison...they are all good.

We do the Precision EFI tunes/flashes.

Just did a Stage 1R and also a 800 Cat

My brother-in-law has a 280hp PEFI tune in his 17 ZR9000 and that thing is scary fast. I have before never felt so much pull yet at over 100 mph.

What clutching is he running?

Something from Speedwerx. His tune is from Speedwerx which is actually a re-branded PEFI tune.

What are your thoughts on the 1R tune?
I really like the bling factor of the air intake/filter.

 

[J & J Racing]

The air intake works well and makes hp
Fit and finish is top notch
Everything they make makes advertised hp

I run a 3r and the 250 setting is awesome
It would just be a bit quieter with stock muffler

for clutching I run STM weights

 

[MrSled]

I wonder how their cold air intake accepts the new rollover hose for the 2020

 

[J & J Racing]

I would bypass it or if not bypass it run the rov hose down through tunnel by chaincase.

Seems to build up a lot of crap where you don’t want it.

It sure does. Bypass it where if not out the tunnel bottom?

 

[J & J Racing]

I meant bypass rov itself and remove it or run rov if there has been no issues on new ones and run hose out through tunnel by chaincase in same way

From our experience, it runs very well and with a great clutch kit, the system rocks!
