New Tune On Vortech

but i hope both of you two gentlemen have long FI setups and make us eat our words

you do realize that you can blow your motor with a Greddy Kit and 5.5 PSI of boost right? because the ECU gets wacky with the Timing and BOOOOOOOOOOOM

You mean pulling timing when it senses knock. That's there to keep it from going boom.

zzero, not sure I had it, for like 2 weeks never installed it, decided to with with UPREV, the new stuff they having coming out, which I am guessing not many people know about. I have been using them for a while. They have done alot of work on and with my car. I bought it back when cipher came out.

I guess you already have oil cooler?

I've got an old Earl's laying around. It's been on several cars from Porsche to Pontiac. No kidding. I just don't feel the need for it. Easier just to change the oil at 2K miles. Oil pressure's good(shrugs).

the stock ecu cant read boost, it just meters air through the MAFS and im guessing they just offset the voltage when they flash it. When you use and aftermarket ecu such as the utec, it gives it the ability to run on speed density instead of mafs voltage so you can actually control injector pulse width relative to rpm and load rather than just tricking the ecu into thinking voltage is lower.
much more accurate and stable imho
Personally having a TN reflash that on MY car never ran right-likely due to my additional mods making it lean, I will say this.... I know Technosquare has a few guys in PR tuned @ 8psi on Greddy kits with no issues (a few on here who I havent seen in a while), and I know those guys run their cars hard. If you flash all 3 of the ECU's maps the timing wont be funny it will always be the same parameters. I dont think its the best option, but I do believe it can be done in most stock block cases with "success"
Just my 2 cents
Just my 2 cents
They told me they're still using the MAF and O2 sensors. My AFR is a flat 11 within a couple of tenths (+ or - .2). With the ss box piggyback that had a boost sensing connection my AFR was all over the place between 9 and 12 AFR. What is speed density? What sensor does it hook up to. I have an 05 with the wideband O2 sensors. That could make all the difference. I don't know. Doesn't the UTEC only adjust timing +-2 degrees. That's not much.
