i have the boost cut raised all the way up so its not affecting the tune but i think its the maf being maxed out now cause some times ill hit it and it pops just like boost cut like its cutting fuel and i have to let out, i know im towards the limits of my top load cells right now on my map, but does the maf have a cut off as well or do i just have to rescale my load tables higher.... any recomendations?

 

You might have to scale your load tables.. **HOWEVER** replace your plugs and gap them at .022 first..

 

thanks, i will regap them and try it, could the maf be seeing to much air to quickly and making it cut off as well? it seems to be doing this now that the air is cooler at night and it feels like when i hit the factory boost cut off, it pops and falls on it face like the fuel just cut out

 

is this gear dependant?

I know in my car a second gear roll from 5k rpm will cause the car to shutter for a few seconds and i've traced it back to misfires due to a weak igntion.... i should add that this is at 31psi

 

i got the plugs gapped at .026 right now and when it does it, it feels like boost cut it breaks up so bad you have to let out

 

Seriously, try closing the gap a bit.. Its probably due to some level of misfire.. My plugs were gapped at .026 even with the HKS DLI-II and it would break up severely even at fairly low boost levels on my GT35r.. I found gapping down to .022 totally eliminated all of the misfire I was getting.

Its easy enough to do to rule it out..

 

Its definitely misfire.. I had it happen at exactly 5000rpm till I regapped my plugs..

If you have an aftermarket CDI, (The HKS DLI-II) I think it may transition from CDI to Inductive at that point.. so that is where my misfire started...

The stock coils are weak in general, that is why they use Iridium plugs since a pointed electrode focuses all the energy in one place, and will jump the gap easier.. But if you have misfire, then you need to close the gap a bit more.

 

i actually have tham gapped to .020, as long as my plugs are new i don't have a problem, they tena to crap ot after about 3k miles, so i keep lots of plugs around the garage.
