boost questions
ok here's what happened my tuner tuned my car several times because my ecu was fighting my piggyback but we've fixed that the problem. On my first tune my car used to produce more boost and more power(more power i think because i can feel the shifting), but as soon as we fixed the problem my car started having lower boost and I think less power but the my tuner told me that im still having the same whp and toque...? is that possible ? why is that i used to produce more boost before compared to my new tune..?

Does your tuner have the maps for each tune?
If so get them printed and compare tune.
Also what kind of civic? year? motor? turbo setup? piggyback? stock ecu or chipped?
I don't know a whole lot about tuning but atleast with this info maybe someone can help you further.
As I see it, 1st set of tunes felt like more boost in the shifting, but ecu was fighting it? What was it fighting? More boost in the shifting?
If you're producing the same whp and wtq then he could have turned the boost up/down and added/removed fuel/air I mean there is alot of things he could have done.
Get the maps if possible and compare.
Is your tuner a reputable tuner for your model/engine/piggyback/setup?

ofcourse its possible .. ur tuner is one of the best .. and my old tuner made 164 whp at 5.5 psi .. and my new tuner (tony) made 181 whp at 5.5 psi ... so yes .. i could put down 164 whp with 4 psi possibly ... so boost doesn't mean power always .. if ituned rightt, u can make the most power and with minimal boost required .. ur tripping .. if tony said its the same whp/tq, i wouldn't doubt it jus cuz "ur shifts feel less power"

Re: boost questions
Post your injector correction and target AFR maps and we'll see what we can do. Also post what injectors you are running.

yey emjay i know tony is the BEST man!
im glad i went to him. i'm just not producing the same amount of boost that i used to have... but he never changed the load X RPM. He just changed the a/f to run little rich when boosting. I have no doubt with his tune prolly its just boost leak or sumting? bad bov? wastegate ? or bad connection? hows you project going on man? i'd like to see those numbers man.. empty ur inbox!! im gonna ask you bout graham's prices..

wastegate ? i never had any WG problem before its fully opening and closing. here's what my car is doing it used to build up boost quickly from 0-8psi but after my tune my boost goes 0-4 and slowly climbs up to 8 and slowly pulling after passing 4psi .. not sure what the problem. could it be a boost leak? im gonna check it out later for any boost leaks

Re: boost questions
Although I don't know too much about turbos, I would agree with diamian, to really tell what's going on, you would have to see the maps. *** dyno's are never reliable, heh my *** dyno rated a net gain of 35 horsepower when I changed the oil!
