well i just installed my liquidtt display. I understand the read out is from the ecu and not mechanical for boost... with that being said. Assuming this reads fairly close to correct my car is running 17.2 psi... As far as i knew my car was stock minus suspension when i bought it. My guess is it isnt a chip but maybe a downpipe? I doubt a chip only adds 2psi so perhaps a dp... I will jack it up and take a look tm. I also have a new TIP so maybe im chipped and the elbow is crushing making me restricted to 17psi. who knows. I havent seen any software for a 225 under 19-20 psi... Uni and GIAC are both files of around 20-23... The kid i bought the car from lives near an apr dealer so maybe it is APR chipped..

any thoughts?

 

I think you are stock.

 

stock = 1bar which = 14.7

my car = 17.2

 

no need to jack it up to check for DP... call up previous owner maybe?

 

also, I dont suppose you were going uphill or otherwise under extra load when reading the psi? are you peaking or holding at 17? I am chipped, but I obivously max out at different psi in different gears and under different conditions. Speaking of which I am almost positive I was at just over 18 the other day and I heard the yellow spring in the forge give it up, might have to check it out or try the green plus two shims.

 

i have a 180 and peak 22psi so who knows... haha, try to figure out if your chipped

 

it was a flat road. The previous owner is a moron... He said it had exhaust and it was very loud. The car was in a fender bender out of that he got a new rear bumper and new exhaust. So he replaced what was on it with OEM catback. The exhaust on these isnt really loud unless it is dp and catback so that is my guess. I think he bought it modded. Im going to run the cable and put the display in 100% tm and i will go out and to multiple pulls to see what it holds. I say 17.2 and looked up... It was 17psi when i was at like 5500rpm though. Even then stock spikes 14.7 and drops correct? Or do they spike higher and hold 1 bar

 

I have the 42DD/Blueflame, and spike at 21psi before the N75 kills the fun and brings it back to 14, and I am stock tune...

 

mine would spike to about 16-17 then taper down and hold 15ish was higher when going uphill or driving with ac on only mods were shroom filter blueflame catback greddy BOV and boost gauge.

Couldn't you run some graphs of your boost using your new liquidtt

 

My Stewart Warner gauge said I'd hit 17 every now and then, back when I was on a stock ECU.
