hey guys

just installed my 90mm
and then i took it for a test drive felt great part throttle and everything

then after i was confident in my install i floored it

truck bogged really hard!!! and said "reduced engine power"
i have the dr X harness and a 90mm has anyone ever had this problem? i was under the impression this was just install and go bolt on

anyone have this problem?

thanks

Well first thing and an important factor, has your tune been attended to for the changes you made with the tb/intake?

 

for my intake manifold yes

for the tb no

Well then you will certainly have to address some other areas in your tune then going from the stock tb I assume up to the 90mm.

 

Another question for you, what is the throttle body off of? Is it the car style or the truck style? Did you buy it new or used?

 

He bought it from me, it was on an 04 silverado with the Xlink he has. The combo works together, he just needs to figure out the tune side of things it sounds like.

 

I had the same problem when my x-link died on me I ended up switxhing to the 02 tac module with no issues

 

I am sure you threw some codes also not just reduced engine...what are the codes?

 

didnt check, i put my 78 back on so i can drives it again engine light dissapeared

i phoned my tuner and i dont know why but he said that it wasnt the tune i kinda think that it is... but then again im not a tuner..

but um he said that the throttle body was the problem.. but how can that be people on here (including Cody) ran this exact set up, he said that the LS2 throttle body works instantly im interested in trying this to see if it works but at the same time i kinda think hes wrong and that he could tune my problem out..

ill let you guys know if i can get some tuning time with him... hes busy all the time and very hard to get a hold of

oh and when i floored the car when the car is off the reduced engine power message came on (car off) he told me to do this but i dont know why really...

PS.
PRC heads are here

 

when my x-link failed i just plugged in my 78mm not even bolted on to the intake and all codes cleared, then plugged in my 90mm and back to reduced engine......that is how i narrowed it down to the x-link....i just got an adapter harness for the 90mm and an 02 tac module.
