Thanks for all your input finally my car pulled a code went to AutoZone said it was a vacuum leak hunted and sprayed everywhere under the hood turns out it's a throttle body already got a GT500 60 mm being shipped to the house
To answer your question about who tuned it these cams don't require a tune.. just trying to ball on a budget.. Lol
Interesting.....glad you found your source of the vacuum leak!
Curious here.....if I may ask, where on the defective TB did you find the vacuum leak? Was it on the TPS side, the actuator side or both sides thru the BF shaft outer seals or was it due to a warped mounting flange surface so it lost sealing integrity on the O-ring in intake manifold? I'm asking this as I'm assuming that you're dealing w\ an OEM FoMoCo 55mm TB, correct?
As for the cams, are they the Comp Cams X-Fi NSR Stage 1 or #127050 cams?
What rocky61201 has typed concerning the amp bronze bushings in particular then following w\ the blowfish racing remote shifter bracket (if you do a lot of shifting under fairly high loads like racing) is something to seriously consider....especially if you're still using the OEM remote shifter....due to what you've mentioned about getting harder to shift into 1st gear & especially harder shifting into reverse but no mention of shifting getting harder into any of the rest.
I'll wager that this is mostly occurring when you're moving the shifter across the gate thru neutral to then go into 1st or reverse while clutch down & car is not moving but no issues shifting into any other gears moving or not, correct? If so this is a symptom of excessive play/slop in the shifter linkage assembly between the shifter handle itself & the gear selector shaft in the trans....ie, the trans gear selector shaft isn't "synched or fully aligned" w\ the shifter handle thus the internal trans gear selector is not quite fully in the outer shift rail gate(s) inside the trans (to access 1st\2nd gear or to fully access the reverse gate rail to then go into reverse) even though the shifter handle is at full side throw thus it has a tendency to "hang" or not go into gear. The OEM shifter linkage bushings are plastic nylon bushings & do wear over time creating excessive play or slop in the linkage.
It don't take much slop in the linkage to create this issue.........
The AMP TR3650 Bronze Bushing Kit that rocky61201 refers to replaces all the plastic bushings in the shifter linkage assembly w\ bronze metal versions to eliminate this "misalignment" thru the linkage & will also firm up the feel thru the shifter handle due to removing any excess forward\rearward slop/play in shifter throw from worn plastic linkage bushings thus improve overall shifting as well.....they're also relatively inexpensive, around $50.00-$60.00 on Amazon.
I've installed these myself & they're worth every cent....
