Either way you go you will be fine, both softwares have pros and cons to them. The plus side of it however is you can modify ANY parameter on the fly. The Custom OS's seem to be better on EFILive as far as features go but in order to RTT you need to purchase a Roadrunner PCM and install it in each car you do. You can only tune a select few tables on the fly but it is a very nice feature to get things dialed in really quick. The great thing about the custom OS's on most of the LS1's is the capability of Real Time Tuning without any extra hardware. Doing this also gives you unlimited custom OS's as well. Then there is the purchase of Unlimited Gen3 v8 Car's which will unlock all LS1 based car's which include 97-04 C5, 98-02 Fbody, 04 GTO. Most of the 99-02 OS's have crazy resolution in the VE table. The reasoning behind this is when you do want to run more than 14-15psi of boost you can easily upgrade to a 3bar sensor and then apply the correct map sensor calibration and then you'll be able to use the rest of the VE table. The reason being you can still use a 2bar sensor with the 3bar OS, it just wont use all of the VE table. Do not waste your money on a 2bar SD OS, if you do any SD OS's do the 3bar OS. It'll also ask you to use more credits to use a custom OS such as 2bar or 3bar SD. Going with all forged bottomend, 317 heads, pt91,5mm etc. Tryed to search but didn't really find the answers I wanted. HPT no longer locks to the vin or pcm ID, but a variety of items in the PCM. Should I continue to to use fix and try to use this version?įast, the 545RFE is a lame duck trans IMO. ※ Download: ?dl&keyword=hp+tuners+unlimited+credits+crack&source= Using HP Tuners Without Application Key or Account Info?
