So I am running the 87 performance tune for the k&n cai. Is it okay to tow with this setting? I tow a 5000 pound travel trailer. There is no canned tow tune. I checked their website and couldn't get a definitive answer. Tempted to go back to stock intake with gotts mod and use stock tune when towing if necessary. Ur input is appreciated.

 

ive heard thats its bad to tow with a performance tune, but ill let the experts answer

 

Unless it's stated unequivocally that it's tow-safe or even tow-tolerant up to a certain load, I would NOT risk it.

In almost every case, I see the tow capability limit/restriction published for custom perf tunes. In absentia, err on the side of caution.

You may wish to find a custom tuning Diablo shop and get a max tow tune in the octane of choice.

Stay safe - put on the stock intake and load the OEM calibration - only takes a couple/few minutes.

Just IMHO ...

Just checked on diablosport.com forums and this is what they say for what its worth.
Post subject: Question on towing-2003 silverado 5.3 u7195*Posted:I occasionally tow with my truck and I was wondering what the weight limits are with each of the tunes available with the predator ( 87, 93 octane).



P.S.



We want stickers!!!

Thanks

I also put in my own topic on the diablosport website and will see what the so called experts say. Updates to follow when they reply.

 

If they are tow rated to max specs, then they are certainly NOT 'Perf' tunes!

They are, like the stock calibration, Compromise tunes.

Just wow.

DiabloMike - you should be ashamed .

Looks like - if you want non-genericized tuning on this platform you MUST get custom calibrations.

Diablo is now formally delisted on Bubba's Christmas list.

Hmmmm .... Gettin' to be a nice dogpile growing here - Diablo, BullyDog, Hypercrap, CS/CTS for '09+, Jet, Banks, ... need a bigger trash bin

Mr Mgd do u think they could email custom tunes that could be loaded for towing. The local custom tuner that I got a hold of wanted to charge 175 for first hour on dyno and 150 per hour after that to custom tune my predator. There are two others in my area but I haven't checked with them yet. All I have is intake and exhaust, there has had to be tow tunes written for same setup in the past. Just wondering if they can be emailed and loaded.

 

Here is the problem. With that intake, you need a tune that is written for it. Either a custom tune or Diablo's adaptable for that intake tune. According to Bill at PHP, you shoud never tow over 2500 lbs with a performance tune. So, in my opinion, what you need is a towing tune written for that intake. The towing problems stem from the changes in the transmission tuning, if you don't have a custom tune.

 

Yer at it again.

The tow capability of a given custom, or canned, calibration is specific to whomever wrote it - TP's for example strictly prohibit ANY towing on their per tunes. VMP's are another example. Superchips, Edge - again, all different. So a blanket statementt like yours is both incomplete, innacurate and misleading.

Additionally - there are also changes in A/F's - true tow tunes run slightly richer to offset the rise in EGT's the extra loads induce. Torque management is different as well, and several other changes in support of optimized towing behaviour.

My previous assertion stands - being a Mod, you should be a bit more discerning about the facts you post - people tend to take yer advice at face value. This information is already present on this forum so there is no real excuse for this - in other words, you can't simply say: "oops - I didn't know ...". Noobs can - you shouldn't.

And - my advice to still stands for whomever is going to listen after you are through - ALWAYS consult with the actual entitiy that wrote the tune for this infomation. It WILL be different.

If you find this rather blunt or inappropriate - report me.

I fail to see anything wrong with what I posted. Bill has stated that you need the low end torque of a towing tune to keep from stressing the transmission. A performance tune does not give that low end torque. he stated that you could tow about 2500 lbs with a performance tune, safely. Where is the error in that? Oh, and you're reported.

If I am wrong, just tell me where, but guess what, I will be wrong again, I'm sure, but you better never make a mistake.

 

Well Mr bluejay the tune is an 87 performance tune for k&n cai. Just for what its worth. I am waiting to hear back from diablosport with my questions. Have a post on their website forums. U and Mgd must have a past I see. Well good luck fellas and don't get too worked up. Have a cold one after work if Ur getting too fired up.

 

Actually, anybody except the representatives of the different tuners themselves are all talking out of their collective *****.

There's not a soul on here that can give you any real facts about anything that these tuners do except the people who make the tuner and/or write the tune.

 

I beleive that's what I tried to convey - twice, in fact.

In addtition to relaying anything already published - by the folks writing the tuness/making the products - about "what these tunere do". Information sources: posts by said vendors in this forum, and relevant manufacturer's websites.

No 'MSU' or '****-blowing' here, by me, at least. I'll leave that to the other fella.

MGD

 

so you have a custom tune for the intake??? you have a three valve???

 

They have canned tunes for cai from diablosport on the predator. It is an 06 so indeed it is the three valve.
