Looking for some ideas Sled is not running well

[Klimbing Kitty]

i have a 2010 TM8 RG and i have been unsuccessful at tuning it so far. First off I can not get the boost to turn past 10 and it farts and sputters as I get on the throttle and then cleans up a bit put is not producing anywhere near the power it should be. No boost leeks that I can find. Fuel pressure is at 41 and 14.1 a/f at idle. on boost 11.1- 11.4 on a/f I am assuming it is way rich. I have straight 112 octane in it and I am riding from 4500 -7500 feet usually. Why will the boost not turn higher? secondary injectors? PL box settings weigh off? My other major problem is RPM I am able to spike it up to 7600 at the start of a pull but right after that it holds a steady 6900 to 7100. is my clutch put together wrong? deflection way off? where should I start to look?

Thanx for any advice guys

turn fuel pressure down to 38lbs and shoot for 12.5 A/F whos kit is it without secondary injectors your only good for 8lbs of boost i just reread it mine is a pure logic as well its a great thought out kit im new to the turbo world myself though

it is on OVS race gas kit an it does have secondary injectors. i am just wondering if they are not working and that is why it will not build anymore than 10 pounds of boost??

running rich will make it not reach full RPMs and fart and sputter just as you say it does......11.1 -11.5 wont run worth crap on my M8, turn the fuelk box down till you see 12.3ish.....and you better have good race fuel if you get above 12.8

or you can simply turn down the fuel poressure, as the fuel box just sends a scaled signal to each injector, it has no clue what fuel pressure you are running
