S197 or S550? just curious if this is with or without IMRCs
Just curious what's been your experience as far as lower end difference between the IMRC's locked versus functional on S550? There is so much BS with these everywhere wondering if there is actual data between the two
Any change in boost from the intake?
Bill- what rpm were you revving the stock manifold to- the 18 manifold will show most of its gains from 6k to 7500 rpm where the stock one was starting to fall flat from 6800ish on up.
Will be interesting to see the results- good write up as well.
Just bought an 18 intake manifold for my 13 5.0 with the mmr lockout kit what else would I need to install this on my 13 5.0
Your numbers are not that far off, the 18 intakes dont add all that much peak power however you should not be having any driveability issues as this is a pretty basic setup unless your running an oddball throttle body which I did not see in your post, find a new tunerGuys need a little guidance with an issue, I have a 2017 GT conv and had a local HP Dyno shop add BBK 1 3/4 long tube headers, 2018 Manifold w/IMRC locked out, C&L intake followed with a custom Dyno tune. After tune the car made 418 RWHP and 382 TQ. I was expecting a bit better but that's okay, the problem is I had the car returned to the shop twice because the 1-3 rpm range drives pretty bad hesitates and lunges makes city driving stop sign to stop sign terrible like someone who doesn't know how to drive a stick lol. Tuner said he has done all he could do and maybe I should enable the IMRC's, the problem with that is I left all my parts removed there and he chucked them. So my question is have any of you guys got this to work smoothly in this range with a none boosted scenario? Need some direction... The car is a performance/premium package so standard tran, 373 gears and larger tires.
Thanks, Stock throttle body.Your numbers are not that far off, the 18 intakes dont add all that much peak power however you should not be having any driveability issues as this is a pretty basic setup unless your running an oddball throttle body which I did not see in your post, find a new tuner
No clutch just 2018 Intake, Long tube headers, C&L air filter and tune. I asked about a leak and he said he doubts it and I left it an extra day so he wasn't rushed. I think he adjusted the ignition timing a bit to get rid of the code. I think I'll just order a tune from VMP and see if it that alleviates the issue. Thoughts?Did you install a clutch or something that you would need to do a crank relearn? Your issue is probably that random misfire, vacuum leak possibly? all this the shop should have checked into but who knows.
