ok so i just installed a Megan catless TBE, Stewart Warner Boost gauge. and bought a halman Pro MBC.. And had a quick question. Would throwing a MBC on the car and raise the boost to @20-21 slow the car down(ie pull timing etc) without a tune? Im ordering a fighters Garage LICP and a couple other things on the car before i get it tuned. Any info would be greatly appreciated thanks Justin

 

Raising it to 20-21psi would be fine.

 

you should be fine

 

No but knock would pull timing and if your boost is too high you will get knock without tuning.

 

Ok so just triple checkin there is no way i should lose power unless the car knocks and pulls timing correct?

well i dont have any way to datalog knock timing etc but i do have a wideband at my disposal so all should be good.... Thanks for all the help

 

Its all fine. I have it on my and I'm running about 21 psi everyday...

 

Your good,the 9 is not going to knock at 20-21psi.

 

thats all i needed to hear thank you

 

Wow.
There are 5 experienced tuners all in this same thread.

 

i installed a hallman pro rx on my IX... 21psi and it pulls haaard... but that's the limit!

 

sorry to thread-jack but what if I got a mail in flash before installing a mbc? Would I need a retune?

 

Im running 28psi but I have meth.....HEHE

 

Wow.
You must be the smart a$$

 

LOL

 

Get a tactrix cable and log with Evoscan.. find out the limit without guessing.
