updates. i had a cracked floor on my fast 90. so i had a idle and driving issue. swapped on the ls2 i had and made my rails work. first thing i noticed is the tune is now rich. ported fast vs ls2 no comparison. the fast was stronger out of boost

ok i been having overboost issues. found them to be im using a tial 60mm gate. read that their springs were rated wrong. basically double. so my 15spring was seeing 30psi with no controller. makes sense why i seen a spike of 25 or so. tossed in the 10 spring and still seen like 20. i was pulling hairs at this point. i put in the 5psi spring and as the guy on tech said i would see double. and i did, i finally was able to go wot with control. the gauge is reading bout 8psi which take into account of pressure drop is right there with 10psi which is double the spring. im going to play with tune for now with no boost controller then hook up controller later on
now as for comparision...at this current moment the truck isnt as fast as my 408. least i dont think so. if i had to compare this combo its probably right there with my 6litre. which im fine with i wanted 1/10th faster then the 6litre to start off at and this way i can get used to the turbo setup.

Tell Quik he has it all wrong. Its not rich, it just isnt getting enough boost.
