I was wondering if you can stack a chip or a programmer on the drag comp? What are the benifits and the downfalls to this? Would yall recomend it? Thanks

Eric

 

drag comp has timing as do the programmers. can you do it? yes. should you do it? NO.

drag comp or the EZ/PM3 stack are the top dogs, hopefully some more reports of the CaTCHER with drag comp or PM3 will come in. gotta look else where as in bigger injectors, turbo(s), etc for more power.

I want to know more about the CaTCHER PCM. How much does it help? What does it do that a box can't do? Thanks

I would stack the superchips tuner with your drag comp. It puts down 30rwhp on a m1750. (Wich everyone knows it reads a little less then a dynojet)

Kyle will have some more input on this. Kyle???

Unless you're running at the track every weekend there is not a large enough benefit to stacking. I spoke with Scott @ TST today for about a half hour about the very same thing. How important is an extra 25hp? Do you think it's worth $500? I don't and $$$ is not a concern of mine.

 

I like the stack for daily driving. It gives me the same bump up in the middle of the power band comparable of stacking the tst+ez. Please note that my truck isn't close to stock and now seems to haze more at idle when the outside air temp is below 40F. I didn't note the normal raise in water temp when the stack was done, but my truck rarely warms up anyways.

Seems like joefarmer and i just had this discussion... like i mentioned in the other post, we've seen gains as much as 30HP and as low as 3HP. The stack works best on trucks that are modified, such as fuel systems, turbo upgrades, high hp injectors. Overall you won't gain a lot more fuel by the stack, but you increase your timing further. I think joe farmer is running some mach series injectors and with the altered spray angles you can run more timing smoother. I'm not an expert on exactly how the angles are modified so someone else might be able to explain it better. I wouldn't recommend running the stack on a daily driver that doesn't have a lot of mods. Best thing to do would be to try one out and see how you like it. Superchips has 30 day money back garuntee on their tuners. If you dont like the way it works send it back.


smokindog: what do you mean by worth $500? are you referering to blowing a head gasket because of the timing increase? it is definatley a possibility as we blew one within 10 minutes running the hypertech stacked.

 

Kyle,

The second thread remarks about the PM3/MAD ECM stack. The MAD ECM is going for $499. The initial question was;

"I was wondering if you can stack a chip or a programmer on the drag comp? What are the benifits and the downfalls to this? Would yall recomend it? "

I was merely answering the "recommend" part of the question based on my conversation with Scott.

If my truck were modified as much as Brandon's I would definitely do it. I agree, 30hp is huge at the track and the benefit of the same may be enough to pull a couple more feet hooked to the sled. I was unaware that a timing increase would blow a head gasket alone with a stock HX35. I thought boost pressures would need to exceed 50PSI on a stock head.

 

__________________________

Do a search on TIP (turbine inlet pressure)
Theres a fair amount of info on overworked singles lifting head gaskets at boost levels much lower than what many guys running twins can get away with. Don M had allot of info on some of the threads and it made it a little eazier to understand.

 

Excessive backpressure will kill you head gasket quicker. (Turbo drive pressure)

Timing increases the pressure in the combustion chamber. LPG, "squeeze", and water/meth are also responsible for increasing the pressures and killing head gaskets.

@ 50 psi of boost with a HX35 you will probably see 80 psi of pressure in-between the exhaust housing and the turbo.

A good way to check for turbo drive pressure is to take out your pyro and temporarily install an oil pressure gauge there and check to see what kind of pressures you are getting at full boost. It may surprise you!!!

sorry, i was assuming no one would stack a programmer with a performance box that has timing...sounds like i was wrong.

my question is this: do programmers adjust the timing? if yes, which ones? i thought they all did, but maybe they change how much fuel is allowed for a certain RPM to give you more power on the low to mid range, without the advance of timing.

could the daily driver stack these two and be safe? the general concensus on this site seemed to be don't stack two timing boxes, thats why i answered the way i did earlier assuming each programmer advanced the timing. EZ (timing) and PM3 (fueling) were fine, but an EZ with a Comp would be bad.

theres always the on going debate whether the EZ is too much timing for an ETH motor (never witnessed anything bad with my 02), but how does that compare with a drag comp stacked with a programmer (again, assuming it advances the timing) for daily driving?

its sounds like the CaTCHER ECM is where its at. great low to mid range, way more responsive. i believe i remember reading it is about the same HP/TQ as the EZ but driveability is greatly improved as far as responsiveness. can be ordered with or without timing, the latter allowing use of a box with timing. but the CaTCHER doesnt have any adjustability, but neither does an EZ.
