Quad 4k rpm issues?

[Sporty01]

Good afternoon guys,

 

so im needing some insight on some issues with my quad 4k box. At the end of June I sent my std module and pulse monitor in to be upgraded. 

 

Upon receiving them back from quad, I hooked the module back up and checked out the updated parameters on the pulse. I created a custom tune took the truck for a quick drive and immediately noticed some popping and that the truck would not turn more than 3450-3500 rpms. I pulled some timing, that fixed the popping up top but the truck still refuses to turn more than 3500 rpms. (I've adjusted the rpm limiter as much as possible). What am I missing? 

 

Truck is an 2001 5spd. It's purely a toy and sled puller. Major mods are 6x16's 66/74 p&p head with fire rings, studs, sprigs, pushrods, fluidampr. 

 

And i I know it's not ideal but I do not have the iQuad yet. Just using the pulse monitor to tune.
