99 GSX/LinkV3/billet 20g/fic1120's, built long block.

Greetings:
I finally have the car on the road, and I cannot seem to be able to boost passed 20psi in 3rd/4th/5th without the CEL tripping. I'm sure its detecting knock, and pulling timing on me. I'm still using a stock MAF, and have not went down the Speed Density route.. yet. I only run 93 or higher octane fuel. My IDC's are normal, plenty more to pull out of it.

Without me postings a log, what do ya'll think could be the problem. Re-wired walbro400, an6 from filter to rail, to FuelLab FPR. Base fuel pressure is fine. My turbo is from Justin , a td06 sl2 20g, and I love it, but only being able to floor 3rd gear at 19/20psi, stinks.. FP manifold, megan o2 housing, 3" to tailpipe... AEM Wideband, logged in link... sheesh.. One thing, if I get into it in 2nd gear, it will steadily hold 20/21psi all the way to 7400RPM?!?!? no CEL, no bucking, etc... any help is greatly appreciated, and if theirs any area I can clear up, just let me know. thanks..

Hey you got a start somewhere I set mine up for the same injectors got it running good. I've been messing with link for years took a a bit but finally got a good grasp of how it works. after strictly dyno tune much better now.

Well, I got my TPS adjusted correctly. It's now reading .63volts at idle. My cruise trims seem.. kinda decent, I believe there lean, but 13.9 to 15.5 swing back and forth it sort of target area. I have my AEM wideband logged in Link, and its almost dead-on. I mean within 1/10th of the gauge reading. What has to happen to star tuning WOT??? same thing as the automatic cruise trim subroutine??

Special thanks to, GST with PSI!!!
Okay, here goes... again.
I have someone kind of local, who makes a 45min trip to come to my house, and tune my car. He was tuning my 96 Talon TSi, and we couldn't get it to boost passed 19psi without the CEL tripping. Well, I broke the transmission in it, and bought a 1999 GSX that needed everything my Talon had, to work. I sourced a 5spd transmission and matching xfer case, verified they are matching, and put the .040 Wiseco 9:1/Scat long block into the GSX, and the ECU/DSMLink from the Talon, into the GSX. I got it all together, made the "Use Non 95/96 Cam sensor" correct, swapped my plug wires, and it started right up. Every single pump/alternator/starter/sensor, etc are all brand new. The engine has BC 272's, BC springs/retainers. Revised lifters, new pump, OEM BSE, balanced, and assembled at a reputable machine shop. I'm running FIC 11200cc injectors, and base fuel pressure is set to 43.5psi, with the vacuum line off, and plugged. Every single intercooler coupler is brand new, with brand new t-clamps, all tightened universally. I made a BLT from parts from the shop, and Lowes, and the system holds pressure to 25psi, then my tool explodes. There are no, black sooty, spots on any of the exhaust(which is also is new). Megan Racing o2 housing, 3" downpipe w/Wideband o2 bung, and 3" pipe to a muffler in the rear. No cat. I AM logging wideband in DSMLink, and am NOT simulating wideband via the front o2.(which is also new). There is no adjustment with my timing, as they are stock gears, and the timing marks all line-up Perfectly. Starts perfect in 25degree weather, and starts right back up, after shutting down. Believe it or not, it doesn't leak anything either. The ignition system consists of brand new coil packs, Magnacore 8.5MM wires, and NGK BR8ES plugs gapped to .025. The turbo, and longblock have, roughly, 9500 Miles on them. It doesn't burn oil, and I have yet to perform a compression test, but I'm 99.9% sure there within 5% of eachother across the board. Every single sensor has been replaced with new ones, 9500 miles ago, except ISC, and TPS. TPS is reading .63volts, and my idle is very good. Every once in awhile, if its been beat on for awhile, the idle will surge to 1400RPM but quickly settle to 1000RPM's. There are Zero CEL's, MIL's, DTC's. I am logging my wideband off the rear o2 pinout, via a wire ran directly to the ECU. It idles at 13.x volts, and under higher RPM's DSMLink shows 14.5volts on a brand new alternator. I don't run any other fuel than Sunoco 93octane pump fuel, and last but not least, not only did I watch the ECMTuning tutorials, but I understood what was happening, but still don't have the hotkey's, and click combo's memorized. I'm running a shoutbend clutch kit, new axles, wheel bearings, inner outer tie rods, and am going in for a 4whl alignment soon. I'm attaching a 1MB log, that shows revs from idle to 7250RPM's, under 20psi boost, and pulls in 1/2/3/4 gear. I can capture a log for ANYTHING, and at ANYTIME, for ANYONE that wishes to see more. Every aspect of the ECU has been made permanent by Chris Martin, my tuner. He's busy, and its hard to get our schedule aligned to setp an hour or 2 of tuning. And, from the feedback I've received from this forum, I may want to look elsewhere for tuning purposes. Thank You!

I'm sure there's thing I forgot to mention. One of them is, I'm running a Walbro 400, and it's re-wired.
